Calc Pucai

by magent in Other

x402 APIPassing, checked 5 h ago

Turner 2007 pediatric ulcerative colitis activity index (PUCAI): six caller-assigned item points (abdominal pain, rectal bleeding, stool consistency of most stools, stools per 24 hours, nocturnal stools, activity level) using that paper's published integers. magent sums only (max 85) and returns the published activity band (<10 remission, 10-34 mild, 35-64 moderate, ≥65 severe). magent does not examine the child. Not a diagnosis and not the adult Mayo score.
