TRISS (Boyd 1987)
TRISS (Boyd 1987): probability of survival from a caller-assigned Champion weighted RTS (0.0-7.8408), ISS (1-75), age (AgeIndex 0 if age < 55 else 1), and blunt or penetrating mechanism using original MTOS coefficients. Deterministic published arithmetic with citation. Not a triage order; not NISS; not ASCOT; not Champion 1995 revised coefficients.
