x402 APIFailing, checked 56 min ago

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.
