^*Hosmer–Lemeshow goodness‐of‐fit p = 0.0865 suggesting a potential lack‐of‐fit. We therefore investigated deviance influence statistics against predicted values and we detected potentially influential points. We refitted the model without those points and the results did not change qualitatively therefore we present the model with the complete data. The c‐statistic for this model is 0.79.

^†Hosmer–Lemeshow goodness‐of‐fit p = 0.9184 and the c‐statistic = 0.83.

AIS  =  Abbreviated Injury Scale Score; CI  =  confidence interval; ipH  =  initial pH; OR  =  odds ratio; rFVIIa  =  recombinant factor VIIa.
