To identify independent risk factors associated with the development of abdominal wall hernia in patients with end-stage renal disease receiving peritoneal dialysis, univariate and multivariate logistic regression analyses were performed using IBM SPSS Statistics version 26.0 (IBM Corp., Armonk, NY, USA) and R software version 4.2.1 (R Foundation for Statistical Computing, Vienna, Austria). A predictive nomogram was subsequently developed based on significant predictors identified through multivariable logistic proportional hazards regression modeling. The model\u2019s predictive performance was externally validated and comprehensively evaluated using the area under the receiver operating characteristic curve (AUC), calibration plots, decision curve analysis (DCA), and Kaplan-Meier survival analysis.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Gender, BMI, hemoglobin, ultrafiltration volume, diabetes, serum creatinine, and catheter insertion method showed no significant association with hernia development.

Multivariate analysis confirmed PD vintage (OR = 11.09; 95% CI: 3.64\u201363.59), albumin (OR = 0.24; 95% CI: 0.11\u20130.41), and age (OR = 1.20; 95% CI: 1.15\u20131.27) as independent predictors. The nomogram achieved an AUC of 0.823 in the training cohort and 0.747 in the validation cohort.
