  1. The logistic regression model was adjusted on well-established predictors of mortality, previously listed by a group of experts on a Delphi [17] and on confounders of early platelet transfusions identified on bivariate analysis (p < 0.2). Early platelet transfusion was defined as platelet transfusion within the first 6 h. Odds ratios with 95% confidence intervals [OR (95% CI)]
  2. Akaike criteria 810
  3. Calibration: Hosmer–Lemeshow test p = 0.117
  4. Discrimination: AUC 0.93, 95% CI (0.91–0.94)
  5. *p < 0.05
