Nomogram to identify the risk of AKI following AP, based on logistic regression analysis. To assign scores to each variable, av vertical line is drawn upward to the “Point” axis, and the corresponding value is recorded. The sum of all predicted scores is then located on the “Total Point” axis. By drawing a line downward to the “AKI Possibility” axis, the likelihood of development AKI can be determined. The abbreviations used are as followings: SOFA: Sequential organ failure assessment, WBC: White blood cells, Alb: albumin, CHF: Chronic heart failure
