Heart‐rate–independent analysis. Mean difference in QT interval (in percent) between the three other groups and those who had never taken menopausal hormone therapy. Data are shown in heart rate bins of 5 bpm from 55 to 94 bpm. In almost all bins, subjects taking unopposed estrogen therapy had QT intervals that were longer than each of the other groups. See text for details. Data are shown as mean ± SEM. COMB = combine estrogen and progesterone use; EST = estrogen use alone; MHT = menopause hormone therapy
