Evaluation of the effectiveness of the nomogram
AKI
In the training cohort, the AUC value was 0.795 (95% CI, 0.758–0.832). Further, the BISAP, Ranson, and APACHE II scores showed AUC values of 0.638(95% CI, 0.593–0.68), 0.706(95% CI, 0.664–0.748), and 0.734(95% CI, 0.693–0.776), respectively. The differences were statistically significant ((A,B) ROC curves of the nomogram, BISAP score, Ranson score, and APACHE II score for predicting the likelihood of developing AKI in AP patients.
