Clinical use of the nomogram
AKI, non-AKI
DCA was plotted with net benefit as the ordinate coordinate and high-risk threshold probability as the abscissa. The results showed that the nomogram had a good clinical value. The DCA revealed that patients had a higher net benefit than BISAP, Ranson, and APACHE II scores, as shown in DCA of the nomogram, BISAP score, Ranson score, and APACHE II score predict the early occurrence of AKI in AP patients; A is the training cohort, and B is the validation cohort. Note: The pink dotted line (None) represents the net benefit rate in the non-AKI group, while the purple dotted line (All) represents the net benefit rate of the AKI group.
