CVD, cardiovascular diseases; non‐HDL cholesterol, non‐high‐density‐lipoprotein cholesterol; OR, odds ratio.
Of the 3482 women, 595 did not have values of those variables at >1 point in time (ie, they had those values at baseline only and dates of CVD onset).
Mean differences were adjusted for baseline age, body mass index, systolic blood pressure, non‐HDL cholesterol, smoking status, alcohol drinking, and treatment for diabetes mellitus, hypertension, and dyslipidemia by multiple regression analyses.
ORs were adjusted for baseline age, body mass index, systolic blood pressure, non‐HDL cholesterol, smoking status, alcohol drinking, and treatment for diabetes mellitus, hypertension, and dyslipidemia by multinomial logistic regression analyses.
