Comparative Predictive Value of Pre-hospital and In-hospital Delays for Acute Gangrenous or Perforated Appendicitis: Analysis Using LASSO Regression and Restricted Cubic Splines
This study demonstrates that pre-hospital delay is a superior independent predictor of gangrenous or perforated appendicitis compared to in-hospital delay, with risk escalating nonlinearly after 24 hours of symptom onset, thereby informing clinical triage and risk stratification.
