FSH: follicle stimulating hormone, Q: quartile, SE: standard error;
Unadjusted, untransformed mean total cholesterol (mmol/L), low-density lipoprotein cholesterol (LDL-C, mmol/L), high-density lipoprotein-cholesterol (HDL-C, mmol/L), and triglycerides (mmol/l). P-value from ANOVA
Lipid levels log transformed to improve normality in all regression models. Model 1 adjusted for age (continuous), year of study entry (continuous), estradiol (quartiles), testosterone (quartiles), sex-hormone binding globulin (quartiles), age at menarche (above and below median), last menstruation age (above and below median), duration of oral contraceptive use (above and below median), duration of hormone therapy use (above and below median), history of hysterectomy (yes, no), history of oophorectomy (yes, no).
Model 2 adjusted for model 1 covariates and systolic blood pressure (continuous), diastolic blood pressure (continuous), smoking status (never, past, current + pack-years above median; current + pack-years below median), physical activity (quartiles), body mass index (continuous), and waist-to-hip ratio (continuous).
Model 3 adjusted for model 2 covariates and use of lipid lowering medication (yes, no)
