All pediatric patients under the age of 18 years diagnosed with acute pancreatitis (AP) were included. The primary predicted outcome was the probability of children with AP progressing to SAP. We used the Least Absolute Shrinkage and Selection Operator (LASSO) regression to select optimal predictors and logistic regression to build a nomogram. The model's performance was evaluated using ROC curves, a Calibration Curve, and Decision Curve Analysis (DCA). Internal and external validations were performed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      For the training cohort, we enrolled 152 pediatric AP episodes, among which 23 episodes (15.1%) were categorized as SAP. In the external validation cohort, we included 60 pediatric AP episodes, with 7 episodes (11.7%) being classified as SAP. The nomogram, based on fever, C\u2010reactive protein, blood urea nitrogen, albumin, and calcium, showed good performance with an AUC of 0.875, sensitivity of 0.913, specificity of 0.76 in the training cohort and an AUC of 0.97, sensitivity of 0.857, specificity of 1 in the external validation cohort.
