NM: Natural menopause, HOC: hysterectomy with ovarian conservation, HBSO: Hysterectomy with bilateral oophorectomy, LV: Left ventricular. E/A: mitral ratio of peak early (E) to late (A) diastolic filling velocity
Model adjusted for each respective year 5 echocardiographic parameter and covariates [age (continuous), race (black, white), education (less than high school, high school or more), center (Birmingham, Chicago, Minneapolis, Oakland), BMI (continuous), waist girth (continuous), physical activity (continuous), parity (none, one, two, three or more), current smoking status (yes, no), current oral contraceptives (yes, no), current alcohol use (yes, no), family history of CHD (yes, no), systolic blood pressure (continuous), diabetes (yes, no), age at menarche (continuous), HDL (continuous) and total cholesterol (continuous)].
Echo parameters measured only at year 25
P value comparing women with natural menopause to surgical menopause (HOC + HBSO)
P value comparing women with HBSO to women with natural menopause
P value comparing women with HOC to women with HBSO
P values were adjusted for multiple comparisons using Tukey-Kramer method
