Jin 2018 ED model for early diagnosis of acute pancreatitis when lipase is at le

Jin 2018 ED model for early diagnosis of acute pancreatitis when lipase is at least 3x ULN. Integer points: prior episodes 0/1/2/3/4, cholelithiasis +2, abdominal surgery in 2 months -2, epigastric pain +2, worsening pain +1, pain duration >=5 days -1, severity mild 0 / moderate +2 / severe +3, lipase fold +0/+1/+2. Score max 14; jin2018_high_ppv if score>=8; jin2024_accuracy_cut if score>=6. Not a diagnosis. Not an imaging order. Not Ranson, BISAP, or Glasgow-Imrie.

Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
