Cholesterol jumps in the year around your last period. At Longevity Benchmark, the guides we publish start from what clinical research and regulatory labelling actually measure, rather than marketing claims. This surge in atherogenic particles is tied to ovarian changes rather than chronological aging alone. Guidelines treat premature menopause before age 40 as a risk enhancer and natural menopause as neutral, so the same LDL-C number can mean two different things.
Aggregate averages hide the change, because HDL-C moves the opposite way to LDL-C across the transition. Circulating estrogen directly influences hepatic clearance of low-density lipoproteins. When ovarian production declines, circulating total cholesterol, low-density lipoprotein cholesterol (LDL-C), and apolipoprotein B (apoB) increase simultaneously. However, high-density lipoprotein cholesterol (HDL-C) levels often remain stable or rise, creating a misleading impression of vascular protection.
The Verdict
Magnitude of Cholesterol After Menopause and the Transition Window
Total cholesterol, low-density lipoprotein cholesterol, and apolipoprotein B increase substantially during a two-year window centered on the final menstrual period (FMP). Data from the Study of Women's Health Across the Nation (SWAN), published in the Journal of the American College of Cardiology, tracked 1,054 women through natural menopause across 10 annual examinations. Researchers compared linear models representing chronological aging against piecewise models representing ovarian transition. Total cholesterol rose by 2.98 mg/dL per year prior to the final year, jumped by 6.47 mg/dL during the transition year, and plateaued at minus 0.16 mg/dL per year thereafter.
Atherogenic particles follow an identical sharp inflection. In that same SWAN cohort, LDL-C climbed 1.57 mg/dL a year until roughly 12 months before the final period. Inside that final year it surged to 5.20 mg/dL. Afterwards it slowed to 0.14 mg/dL a year. ApoB increased by 0.67 mg/dL per year before, surged by 3.24 mg/dL annually during the transition window, and declined by 0.40 mg/dL annually post-transition. Other cardiometabolic markers behaved differently. Fasting glucose, tissue plasminogen activator antigen, and fibrinogen followed linear aging models without a transition-specific acceleration.
This localized surge produces measurable vascular changes. A SWAN carotid artery analysis published in Stroke followed 863 postmenopausal women and observed an LDL-C rise of 6.71 mg/dL per year during the transition window. Each unit increase in LDL-C during this period was associated with higher odds of carotid plaque (odds ratio 1.071, 95% confidence interval (CI) 1.018 to 1.127; P = 0.009). Arterial stiffness accelerates during the same period. In an analysis in Arteriosclerosis, Thrombosis, and Vascular Biology examining carotid-femoral pulse-wave velocity, arterial stiffness increased by 7.5% per year within 12 months of the final period, compared to 0.9% before and minus 1.0% afterward.
Research presents slight variations in the attribution between ovarian changes and chronological aging. In an earlier SWAN publication in the American Journal of Epidemiology evaluating 2,659 women, total cholesterol rose 9.33 mg/dL across the transition compared to 6.52 mg/dL attributable to 4.84 years of chronological aging (P = 0.07). The authors concluded transition-related changes did not achieve statistical divergence from status-adjusted aging alone. However, the 2020 American Heart Association (AHA) scientific statement published in Circulation reviewed these findings and concluded that increases in LDL-C and apoB are driven by the menopause transition more than chronological aging.

Hepatic LDL Receptor Regulation and Estrogen Loss
Declining circulating estradiol reduces hepatic low-density lipoprotein receptor activity, slowing the clearance of atherogenic particles from systemic circulation. In a classic metabolic study published in The New England Journal of Medicine, researchers administered oral micronized estradiol to postmenopausal women to measure lipoprotein kinetics directly. Oral estradiol at 2 mg daily reduced LDL-C by 14% because LDL catabolism increased by 36% (P < 0.005). Simultaneously, estradiol increased large very-low-density lipoprotein (VLDL) apoB concentration by 30% through an 82% acceleration in production rate. The trial demonstrated that estradiol accelerates both the clearance of LDL and the synthesis of triglyceride-rich VLDL particles.
Delivery route alters this hepatic mechanism completely. The same investigation showed that transdermal estradiol administered at 0.1 mg twice weekly had no measurable effect on circulating lipoprotein concentrations. Because oral estrogens pass directly through the portal circulation to the liver, they exert a first-pass effect on hepatic protein synthesis that transdermal administration avoids. Animal models corroborate the cellular role of hepatic estrogen signaling. A study published in Molecular Metabolism demonstrated that female mice lacking hepatocyte estrogen receptor alpha developed impaired reverse cholesterol transport and a 5.6-fold larger atherosclerotic lesion area compared to wild-type littermates.
When natural ovarian estradiol secretion falls during perimenopause, hepatic clearance rates drop. With fewer active receptors clearing circulating particles, intermediate-density and low-density lipoproteins remain in plasma longer. This prolonged circulation time increases susceptibility to oxidative modification and endothelial penetration. Total particle concentration expands accordingly. nuclear magnetic resonance (NMR) lipoprotein subclass measurements in SWAN, published in Menopause, showed that total LDL particle count grew by 38.11 µmol/L annually during perimenopause, compared to annual declines of 11.24 µmol/L premenopause and 3.56 µmol/L postmenopause.
High-Density Lipoprotein Function and Lipoprotein(a) Patterns
High-density lipoprotein cholesterol frequently remains stable or rises across the menopause transition, while its vascular protection appears to diminish. Clinicians frequently encounter postmenopausal lipid profiles displaying elevated total cholesterol alongside high HDL-C, which standard risk calculators can misinterpret as favorable. In a SWAN sub-study published in the Journal of Clinical Lipidology following 213 women, greater increases in HDL-C across the transition were significantly associated with greater carotid intima-media thickness progression (P = 0.008). Higher baseline apolipoprotein A-1 was associated with lower progression, indicating particle quality diverges from aggregate cholesterol content.
The 2020 AHA scientific statement highlighted this functional shift as an apparent reversal in cardiovascular associations. Before menopause, higher HDL-C levels correlate with lower carotid atherosclerosis; after menopause, higher levels correlate with greater plaque progression. Preliminary SWAN research noted in the AHA statement suggests that the initial step in reverse cholesterol transport may weaken during the transition. Because aggregate HDL-C measures the cholesterol cargo carried within particles rather than cholesterol efflux capacity, a rising HDL-C number does not necessarily confirm continuing arterial protection.
Lipoprotein(a) behavior across the transition exhibits conflicting evidence in clinical literature. In the SWAN cohort published in the American Journal of Epidemiology, lipoprotein(a) was reported to peak during late perimenopause and early postmenopause. However, the subsequent piecewise modeling analysis in the Journal of the American College of Cardiology found that linear and piecewise models showed equivalent statistical fit for lipoprotein(a). The data do not demonstrate a clean menopause-specific inflection point for lipoprotein(a), unlike the distinct jump documented for LDL-C and apoB. Testing lipoprotein(a) remains valuable primarily because its circulating concentrations are largely genetically determined and remain an independent vascular risk enhancer.
Pre-Transition Baseline Panels and Diagnostic Utility
Drawing a comprehensive lipid panel before menstrual cycles become irregular establishes a clinical baseline that separates transition-induced spikes from lifelong metabolic trends. Because the total cholesterol and LDL-C acceleration is concentrated within a 12-month window around the final menstrual period, a single test drawn years after menopause cannot reveal how much circulating cholesterol increased during the transition. Obtaining a standard lipid panel along with apolipoprotein B during late reproductive life provides a reference point for future clinical discussions.
Baseline patient characteristics influence the absolute magnitude of transition-related lipid changes. In the SWAN cohort, women with higher baseline body weight experienced smaller percentage increases in circulating lipids across the transition than normal-weight women. Furthermore, chronological timing varies widely among individuals. A 20-year SWAN follow-up published in the Journal of the American Heart Association evaluated 1,554 women and observed inconsistent relationships between age at final menstrual period and lipid trajectories. Older age at menopause was associated with less adverse total cholesterol changes after the final period, but more adverse apoB changes leading into the transition.
Monitoring biomarkers across the stages of menopause helps clinicians distinguish ovarian lipid surges from underlying familial dyslipidemia. Evaluating a dedicated perimenopause biomarker panel allows timely assessment of atherogenic particle counts, fasting glucose, and inflammatory markers before vascular remodeling becomes established. When a midlife lipid panel reveals elevated LDL-C, having a pre-transition measurement informs whether the patient experienced a sudden hormonal escalation or carries chronic hypercholesterolemia requiring different diagnostic evaluation.
Reproductive Risk Factors and Long-Term Vascular Risk
Cardiovascular risk across the menopause transition is shaped by early reproductive milestones that standard midlife lipid panels cannot detect. Premature menopause, occurring before age 40, and early menopause, occurring between ages 40 and 45, truncate lifetime vascular exposure to endogenous estrogens. A systematic review of 32 studies comprising 310,329 women published in JAMA Cardiology found that menopause before age 45 carried a relative risk of 1.50 (95% CI 1.28 to 1.76) for coronary heart disease. Cardiovascular mortality ran to 1.19 (95% CI 1.08 to 1.31). All-cause mortality reached 1.12 (95% CI 1.03 to 1.21).
Surgical removal of the ovaries before age 40 introduces even higher long-term risk. In an analysis of 144,260 postmenopausal women from the UK Biobank published in JAMA, natural premature menopause carried a hazard ratio of 1.36 (95% CI 1.19 to 1.56) for composite cardiovascular disease. Bilateral oophorectomy before age 40 carried 1.87 (95% CI 1.36 to 2.58). This excess risk persisted after adjusting for traditional risk factors and menopausal hormone therapy use.
Complications during pregnancy also forecast midlife cardiovascular vulnerability. A meta-analysis of over 6.4 million women published in Circulation: Cardiovascular Quality and Outcomes documented that preeclampsia independently predicted future heart failure, at a relative risk of 4.19 (95% CI 2.09 to 8.38). Coronary heart disease ran to 2.50 (95% CI 1.43 to 4.37), and cardiovascular death to 2.21 (95% CI 1.83 to 2.66). Gestational diabetes carries parallel risk. A meta-analysis in Diabetologia covering 5.3 million women found a relative risk of 1.98 (95% CI 1.57 to 2.50) for cardiovascular events, which remained 1.56 (95% CI 1.04 to 2.32) even among women who never developed type 2 diabetes. An AHA scientific statement in Circulation emphasised identifying these adverse pregnancy outcomes during midlife risk evaluations, though their formal capacity to reclassify risk scores remains under study.
| Reproductive Risk Factor | Reported Relative Risk or Hazard | Primary Cardiovascular Outcome | Clinical Guideline Classification |
|---|---|---|---|
| Premature Menopause (<40 Years) | HR 1.36 (natural) / HR 1.87 (surgical) | Composite cardiovascular disease | Formal ASCVD risk-enhancing factor |
| Early Menopause (40 to 45 Years) | RR 1.50 (95% CI 1.28 to 1.76) | Coronary heart disease | Clinical risk marker in specialized statements |
| Preeclampsia History | RR 2.50 (CHD) / RR 4.19 (Heart Failure) | Coronary disease and heart failure | Formal ASCVD risk-enhancing factor |
| Gestational Diabetes History | RR 1.98 (95% CI 1.57 to 2.50) | Future cardiovascular events | Vascular risk marker in clinical prevention |
Clinical Guidelines for Cholesterol After Menopause and Statin Thresholds
Clinical cholesterol management guidelines classify premature menopause before age 40 and adverse pregnancy outcomes as risk-enhancing factors rather than independent treatment triggers. The multisociety blood cholesterol guidelines developed with the American College of Cardiology and published in Circulation provide a structured framework for clinicians evaluating primary prevention in adults aged 40 to 75. The guidelines categorize 10-year atherosclerotic cardiovascular disease (ASCVD) risk into four explicit bands: low (under 5%), borderline (5% to 7.4%), intermediate (7.5% to 19.9%), and high (20% or greater).
Treatment recommendations in guidelines depend on baseline risk calculation and specific biomarker thresholds. A guideline synopsis published in the Annals of Internal Medicine outlines the decision architecture addressed to healthcare providers. For adults at intermediate risk, guidelines recommend moderate-intensity statin therapy to reduce LDL-C by 30% to 49% if clinician-patient discussions favor treatment. For high-risk individuals, guidelines recommend high-intensity statin therapy targeting a 50% or greater LDL-C reduction. In borderline risk cases, the presence of risk-enhancing factors, including premature menopause or preeclampsia, favors initiating moderate-intensity statins.
Certain laboratory findings alter the decision process entirely. An LDL-C level of 190 mg/dL or higher warrants high-intensity statin therapy without requiring 10-year ASCVD risk calculation. When intermediate risk status remains uncertain, guidelines suggest measuring coronary artery calcium (CAC). A CAC score of zero Agatston units supports deferring statin therapy in non-smokers without diabetes or strong family history. Conversely, a CAC score between 1 and 99 favors statin therapy, particularly after age 55, while a score of 100 or greater indicates statin initiation. Importantly, a 10-year risk score of 7.5% or higher does not result in automatic statin assignment, requiring a balanced clinician-patient discussion regarding potential benefits and adverse effects.
Hormone Therapy Lipid Biomarkers Versus Cardiovascular Outcomes
Hormone therapy improves circulating lipid biomarkers while failing to demonstrate a reduction in coronary heart disease events in large randomized prevention trials. In the Women's Health Initiative (WHI) trials, published across multiple follow-ups including an analysis in Obstetrics & Gynecology, oral conjugated equine estrogens (CEE) alone reduced LDL-C by 11% over 6 years. Combined CEE plus medroxyprogesterone acetate (MPA) reduced LDL-C by 12% and lipoprotein(a) by 20%, against a 15% lipoprotein(a) reduction with CEE alone. In the 3-year randomized PEPI trial published in JAMA, all active hormone regimens lowered LDL-C by 14.5 to 17.7 mg/dL while increasing HDL-C.
Administration route influences lipid subfractions differently. In a randomized trial published in Menopause comparing transdermal to oral estradiol, oral regimens reduced LDL-C by 12.6% compared to 5.8% with transdermal delivery. Furthermore, an investigation in ecancermedicalscience showed that serum triglycerides diverged sharply by route: oral CEE increased triglycerides by 21.4%, whereas transdermal estradiol reduced them by 8.6% (P < 0.0001). A meta-analysis in Maturitas confirmed that oral estrogen achieved significantly greater lipoprotein(a) reductions than transdermal formulations.
These favorable surrogate biomarker shifts did not translate into coronary protection in randomized clinical trials. In the primary WHI trial of combined CEE plus MPA published in The New England Journal of Medicine, hormone therapy yielded a hazard ratio of 1.24 (nominal 95% CI 1.00 to 1.54) for coronary heart disease. Risk peaked in year one, at 1.81. In the hysterectomized cohort taking CEE alone, published in the Archives of Internal Medicine, the coronary outcome was neutral (hazard ratio 0.95, 95% CI 0.79 to 1.16). A comprehensive review in the Cochrane Database of Systematic Reviews analyzing 19 trials and 40,410 postmenopausal women concluded that hormone therapy conferred no protection against cardiovascular death or non-fatal myocardial infarction. It raised stroke risk (relative risk 1.24) and venous thromboembolism risk (relative risk 1.92).
Prescribing guidelines and regulatory approvals reflect this split between surrogate markers and clinical endpoints. Official prescribing information for Premarin carries a prominent boxed warning stating that estrogen-alone and estrogen plus progestin therapy should not be used for the prevention of cardiovascular disease or dementia (label revised April 2025, DailyMed record checked September 2026). The approved indications cover vasomotor symptoms, vulvar atrophy, hypoestrogenism, and osteoporosis prevention, without any indication for lipid lowering or cardioprotection. Position statements from the Menopause Society reiterate that hormone therapy is not government approved for cardiovascular disease prevention, despite the favorable estrogen therapy benefits documented for vasomotor symptom relief.
| Hormone Formulation and Route | Surrogate Lipid Panel Impact | Randomized Clinical Event Outcome | Cardioprotection Regulatory Status |
|---|---|---|---|
| Oral Conjugated Estrogens (CEE Alone) | LDL-C reduced ~11%, Lp(a) reduced ~15%, triglycerides increased | Neutral coronary effect (WHI HR 0.95; 95% CI 0.79 to 1.16) | Not approved for cardiovascular prevention |
| Oral CEE plus Medroxyprogesterone (MPA) | LDL-C reduced ~12%, Lp(a) reduced ~20%, triglycerides increased | Increased early coronary risk (WHI HR 1.24; Year 1 HR 1.81) | Boxed warning against cardiovascular prevention use |
| Transdermal 17β-Estradiol | Modest LDL-C reduction (~6%), triglycerides decreased (~9%) | Lacks randomized trial cardiovascular event endpoint data | Not approved for cardiovascular prevention |
Lowering Cholesterol After Menopause Through Lifestyle and Statins
Standard lifestyle interventions blunt menopausal lipid increases without fully preventing them, while statin medications demonstrate proportional vascular risk reduction across sexes. The Women's Healthy Lifestyle Project examined 535 premenopausal women through the transition over 54 months. In the lifestyle intervention group, LDL-C rose by 3.5 mg/dL compared to 8.9 mg/dL in assessment-only controls (P = 0.009). The authors noted that lifestyle modifications successfully blunted lipid increases and slowed carotid intima-media thickness progression, but could not completely eliminate the transition-induced rise in LDL cholesterol.
Broad dietary trials move lipids a little and events not at all. In the Women's Health Initiative Dietary Modification Trial involving 48,835 postmenopausal women followed for 8.1 years, a low-fat dietary pattern reduced LDL-C by only 3.55 mg/dL. The intervention yielded no significant reductions in coronary heart disease (hazard ratio 0.97, 95% CI 0.90 to 1.06) or stroke (hazard ratio 1.02). Exercise meta-analyses reflect comparable boundaries. A systematic review in Applied Nursing Research of 17 trials in postmenopausal women found reductions in body fat and triglycerides, but no significant pooled effect on LDL-C. In the Brazilian Journal of Medical and Biological Research, aerobic and resistance protocols in obese postmenopausal women reduced LDL-C by 16 to 18 mg/dL, though authors noted the broader evidence base remains incipient.
When medication is indicated under clinical practice guidelines, statin therapies demonstrate consistent risk reduction in women. A landmark meta-analysis by the Cholesterol Treatment Trialists' Collaboration published in The Lancet examined individual participant data from 174,149 individuals across 27 randomized trials, including 46,675 women. For each 1.0 mmol/L reduction in LDL-C, the proportional reduction in major vascular events was similar by sex. Women fell to a rate ratio of 0.84 (99% CI 0.78 to 0.91) and men to 0.78 (99% CI 0.75 to 0.81), with adjusted heterogeneity P = 0.33. All-cause mortality reductions were also equivalent (rate ratio 0.91 in women versus 0.90 in men).
Scientific consensus acknowledges ongoing discussion regarding primary prevention subgroups. The 2020 AHA scientific statement pointed out that within primary prevention cohorts in the CTT dataset, the event rate ratio in women was 0.85 (95% CI 0.72 to 1.00), suggesting that event reduction data in primary prevention remain less established than in secondary prevention. Nevertheless, current clinical guidelines recommend statins as first-line therapy for indicated cardiovascular risk reduction regardless of sex or menopausal status. Evaluating therapy involves weighing personal history, 10-year risk scores, and coronary calcium imaging rather than applying blanket thresholds.
This analysis is not for women experiencing acute cardiovascular symptoms, those with severe familial hypercholesterolemia presenting with LDL-C of 190 mg/dL or higher, or individuals with established coronary heart disease, who require immediate individualized management by a cardiologist. Our assessment would change if a randomized controlled trial demonstrated that initiating lipid-lowering therapies specifically during the perimenopausal transition window produced superior long-term clinical event reductions compared to standard guideline-directed thresholds. The measurements the guidelines use for this decision are the standard lipid panel and apolipoprotein B, and what each one reports is set out in those guides.
Frequently Asked Questions
Does menopause raise cholesterol?
Yes, menopause causes a distinct increase in total cholesterol, LDL cholesterol, and apolipoprotein B. Prospective data from the Study of Women's Health Across the Nation demonstrated that these lipid particles surge during a one-year window before and after the final menstrual period. This jump is directly associated with ovarian transition rather than normal chronological aging. As ovarian production of estradiol declines, hepatic LDL receptor activity decreases, slowing the clearance of atherogenic particles from systemic circulation. In contrast, blood pressure, fasting glucose, and insulin resistance increase gradually across midlife in patterns consistent with general chronological aging rather than an abrupt menopausal transition effect.
How much does cholesterol increase after menopause?
Total cholesterol increases by an average of 6.5 mg/dL per year and LDL cholesterol rises by approximately 5.2 mg/dL per year during the 12 months surrounding the final menstrual period. In the Study of Women's Health Across the Nation, this rate of increase was roughly three times faster than changes observed more than a year before the transition. Apolipoprotein B levels surge by approximately 3.2 mg/dL annually during this same transition window. After the first postmenopausal year, lipid trajectories plateau, with annual changes dropping close to zero. Women in early postmenopause have more than double the odds of presenting with LDL cholesterol above 130 mg/dL compared to premenopausal women.
What are normal cholesterol levels after menopause?
Clinical guidelines do not define menopause-specific or age-specific normal cholesterol ranges. Instead, the 2018 AHA/ACC multisociety cholesterol guideline outlines clinician-facing decision thresholds rather than patient targets. An LDL-C at or above 190 mg/dL indicates a high-intensity statin without calculating 10-year cardiovascular risk. Readings from 160 to 189 mg/dL represent a risk-enhancing factor. The guideline also applies thresholds of 70 and 100 mg/dL to treatment decisions. Premature menopause before age 40 counts as a risk enhancer. Natural menopause does not. For an individual, earlier personal lipid panels provide the meaningful baseline. Cholesterol shifts notably across this window. In the Study of Women's Health Across the Nation (SWAN), Matthews and colleagues found LDL-C rose 5.20 mg/dL annually within a year of the final menstrual period, compared to 1.57 mg/dL yearly before it.
Does perimenopause raise cholesterol before periods stop?
Yes, atherogenic lipid levels begin rising during late perimenopause before menstrual periods cease entirely. Clinical cohort studies demonstrate that total cholesterol, LDL cholesterol, and apolipoprotein B accelerate in the 12 months leading up to the final menstrual period. In the Study of Women's Health Across the Nation, LDL particle counts grew by an average of 38.1 µmol/L annually during perimenopause, compared to annual declines during premenopause. Arterial stiffness climbs sharply in the same window. Women often observe shifts in their routine lipid panels before experiencing complete amenorrhea, reflecting early alterations in ovarian steroid production.
Does HRT lower cholesterol?
Oral menopausal hormone therapy lowers LDL cholesterol by 11% to 14% and reduces lipoprotein(a) by 15% to 20%, but it is not approved for cardiovascular disease prevention. In the Women's Health Initiative randomized trials, oral conjugated estrogens combined with medroxyprogesterone acetate improved surrogate lipid markers while increasing coronary heart disease events, particularly during the first year of treatment. Hepatic first-pass metabolism also pushes triglycerides up by 20% or more on oral estrogen. Transdermal estradiol cuts LDL about 6% and triglycerides about 9%. Because clinical trials failed to demonstrate cardiovascular protection, hormone therapy labels carry boxed warnings advising against using hormone therapy for cardiovascular disease prevention.
Why is my HDL high but my risk still up after menopause?
A high HDL cholesterol concentration after menopause does not guarantee cardiovascular protection because the functional capacity of HDL particles alters across the transition. In SWAN, the relationship between HDL cholesterol and vascular health reverses at menopause. Before menopause, higher HDL cholesterol correlates with less carotid plaque; after menopause, higher HDL levels are associated with greater carotid intima-media thickness progression. Standard lipid panels measure the cholesterol content carried inside HDL particles rather than their capacity to extract cholesterol from arterial walls. That transport may weaken across the transition, which makes an aggregate HDL number misleading.
Should I get a lipid panel before menopause?
Obtaining a comprehensive lipid panel during late reproductive life establishes a baseline that allows you and your physician to differentiate menopausal lipid spikes from chronic metabolic conditions. Because cholesterol surges in a narrow window around the final menstrual period, a test performed years after menopause cannot determine how much of your current level resulted from hormonal transition versus preexisting baseline elevations. Testing total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides, and apolipoprotein B in your forties provides an objective reference point. This pre-transition baseline enables clinicians to interpret postmenopausal lipid changes accurately and evaluate whether medical therapy or lifestyle adjustments are warranted.
Do statins work as well in women as in men?
Statins produce similar proportional reductions in major cardiovascular events in women and men at equivalent baseline risk. The Cholesterol Treatment Trialists' Collaboration analyzed individual data from over 174,000 trial participants, including more than 46,000 women. For every 1.0 mmol/L reduction in LDL cholesterol, major vascular events fell by 16% in women and 22% in men, a difference that was not statistically significant after adjusting for risk characteristics. All-cause mortality reductions were also comparable. While some clinical discussions note that primary prevention trial subgroups in women have shown wider confidence intervals due to lower absolute event rates, major guidelines recommend statins as first-line therapy regardless of sex.
