Documentation for the externally validated clinical prediction model that underpins the bedside calculator.
Outcome30-day all-cause mortality
PopulationNewly diagnosed adult APL
PredictorsAge · WBC · Creatinine
External AUC0.817
LOCKED MODEL FORMULA
Individualized probability estimate
logit(p) = −11.828 + 0.486 × log₂(WBC + 1) + 0.348 × (Age / 10) + 1.682 × ln(Creatinine + 1)WBC is entered in ×10⁹/L and creatinine in µmol/L. The calculator uses this locked equation without refitting.
