Max FSH predicts cycle cancellations better than current FSH. a Number of completed and cancelled cycles with Max FSH and current FSH data, grouped by Max and current FSH elevation status. + indicates true and - indicates false. b Receiver operating characteristic (ROC) curve for model prediction of cycle cancellation using Max FSH (red), PMax FSH (blue), current FSH (black) or null hypothesis (grey). c Distribution of Max FSH, PMax FSH and current FSH in completed and cancelled cycles. IVF cycles were divided into the subset of completed and cancelled ones and the distribution of their respective Max FSH, PMax FSH and current FSH levels was plotted in red, blue and black, respectively. Completed cycles were plotted in solid lines and cancelled cycles in dashed lines. The Kolmogorov-Smirnov statistic between the distribution parameters for completed and cancelled cycles is noted to the right of each bracketed pair (see Methods for details)
