Comparison of calendar age, age at the last menstrual period and body mass index in the study groups.

Parameter	Group (X ± SD)
	A (n = 40)	B (n = 30)	C (n = 30)
Calendar age (years)	53.6 a ± 2.4	57.9 a ± 4.6	67.3 a ± 7.3
Age at LMP (years)	50.8 ± 4.4	50.2 ± 3.3	50.7 ± 3.9
BMI (kg/m2)	24.6 b ± 3.0	28.5 b ± 4.6	29.2 b ± 6.4

A—women for whom 1–5 years had elapsed since the last menstrual period; B—women for whom 6–10 years had elapsed since the last menstrual period; BMI—body mass index; C—women for whom ≥11 years had elapsed since the last menstrual period; LMP—last menstrual period; n—number of patients; X ± SD—mean ± standard deviation; common superscripts denote significant differences between compared groups: p < 0.001 (^a,b) (ANOVA).
