Lille model (Louvet 2007) from age, albumin, bilirubin at day 0 and day 7, creat

Lille model (Louvet 2007) from age, albumin, bilirubin at day 0 and day 7, creatinine, and PT seconds or INR. formula=pt or formula=inr is required; magent does not swap them. Score 0-1 with the published 0.45 cutoff. Deterministic published arithmetic with citation; not a medical device or a steroid order.
