A flowchart of patient screening for HTG-AP, showing exclusions and final groups. The flowchart details the screening process for patients with acute pancreatitis. Initially, 679 patients were screened, with 393 excluded due to other etiologies. From 286 patients with HTG-AP, 87 were excluded for moderately severe or severe acute pancreatitis. The remaining 199 patients with initially mild HTG-AP were assessed for eligibility. Inclusion criteria included age 18 years or older, complete clinical records, available in-hospital outcome data, non-contrast abdominal CT within 24 hours of admission, diagnosis of HTG-AP and mild acute pancreatitis at admission per the 2012 Revised Atlanta Classification. Of these, 35 were excluded due to chronic pancreatitis, previous pancreatic surgery, malignancy (19), severe comorbidities (11), or insufficient imaging quality (5). Finally, 164 patients were included, divided into 88 in the progression group and 76 in the non-progression group.
