Prognostic factors analysis of ultrasound-guided percutaneous puncture drainage in severe acute pancreatitis with peripancreatic fluid collection

Figure 2 Clinical outcomes stratified by drainage timing and fluid collection type. A: Compares key outcomes between early drainage (≤ 72 hours, n = 70) and late drainage (> 72 hours, n = 64); B: Compares outcomes between acute peripancreatic fluid collection/pseudocyst (n = 58) and walled-off necrosis (walled-off necrosis, n = 76). P values above brackets indicate between-group significance. ^aP < 0.05. APFC: Acute peripancreatic fluid collection.
