Discrimination of the nomogram and internal validation of the nomogram. a The discrimination assessed by ROC curve. The AUC is 0.798 (95% CI 0.772–0.825). b The nomogram was internally validated by applying bootstrap sampling for 1000 times. The optimism adjusted AUC is 0.794 (95% CI 0.781–0.822). c Calibration plot of the nomogram. The nomogram was calibrated for the probability of being high-risk RS. (bootstrap 1000 repetitions)
