3 Figure 2 (a) Calibration curves of the Hunault model; (b) the revised model. Calibration of the models was carried out by assigning the calculated 1-year probabilities of natural conception leading to ongoing pregnancy for each included couple to one of 10 categories, based on deciles, and comparing the average probability in each category to the 1-year Kaplan–Meier estimate.

4 Figure 3 Reclassification of the revised model versus the Hunault model based on 1-year predicted chances of ongoing pregnancy. Kaplan–Meier estimates of the real 1-year chance of ongoing pregnancy, per group. Reclassification was calculated in the cohort that the Hunault model was externally validated upon. Filled points, ongoing pregnant; unfilled points, not ongoing pregnant. KM, Kaplan–Meier. Reproductive BioMedicine Online  , DOI: ( /j.rbmo ) Copyright © Terms and Conditions
