Cumulative pregnancy rate resulting in singleton live birth of the current validation population and the previously reported population of the initial prediction model, calculated by Kaplan-Meier method. Dotted lines represent the 95% CI for the current validation population.

Flow chart of treatment course of women starting CC treatment. Women were censored when not pregnant at discontinuation of follow-up (e.g., still undergoing fertility treatment at September 1, 2011, premature drop out of fertility treatment, or drop out of conventional treatment program). Twin pregnancies were censored before the treatment cycle resulting in pregnancy.
