Premenopausal status was self-reported based on the presence of menses, either regular or irregular periods.
2
Because the total (n = 103) is very close to 100, the column percentages approximate the counts; for example, 37.9% (39/103) were premenopausal women.

Postmenopausal status was self-reported based on 12 consecutive months without a menses.
