Impact of 24-hour urine output trajectories on intra-abdominal hypertension risk in acute pancreatitis patients: Insights from MIMIC-IV database.

It is worth noting that this association did not reach statistical significance in patients with biliary AP, which may be related to its unique pathological mechanism: Biliary obstruction and infection may affect the intra-abdominal environment through independent pathways, thereby partially weakening the predictive power of urine output indicators.[ 45 46 ] In addition, the statistical insignificance observed in women and young patients may be due to insufficient statistical power caused by limited subgroup sample size, rather than effect loss.
