Receiver operating characteristic (ROC) curves and calibration plots of the training and validation cohorts. (A) The area under the ROC curve (AUC) of the training cohort was 0.884 (95% CI: 0.869–0.899). (B) Calibration curve for the training cohort. (C) The AUC of the validation cohort was 0.884 (95% CI: 0.863–0.905). (D) Calibration curve for the validation cohort. Calibration curves were used to evaluate the calibration of the model. The horizontal axis is the predicted probability provided by this model, and the vertical axis is the observed incidence of pregnancy failure. The ideal line with a 45° slope represents a perfect prediction (the predicted probability equals the observed probability).
