Calibration plot of PRN. The calibration plot, (a–d), shows observed against expected probabilities for assessment of the four prediction models with the overall external validation cohort according to the TRIPOD guidelines. The red spike plot shows the distribution of events and nonevents. Green circles indicate the expected probabilities in groups with 95% CI. The green line demonstrates the lower smoothness smoother. The model performance statistics are summarized with EO: exp/obs ratio; CITL: calibration-in-the-large; and AUC: area under the curve.
