Kaplan-Meier estimates of cumulative probabilities of return to ovulation, with 95% confidence intervals and numbers at risk below the x-axis. Median times to ovulation for the 45 mg and 75 mg groups were 170 and 226 days, respectively. Medians for the 105 mg and Depo-subQ 104 groups were not estimable due to the small number of ovulations in those groups. Reference line indicates Month 4 of follow-up.
