Fig. 1

Receiver-operating characteristic (ROC) curves for generalized additive models predicting in-hospital mortality. Base model (AUC 0.757): age group, sex, hospital types; Charlson weights model (AUC 0.850): base and Charlson weights; VW weights model (AUC 0.863): base and Elixhauser/ van Walraven weights; Swiss weights model (AUC 0.867): base and Elixhauser/ Swiss weights. Straight diagonal line in the middle showing null model (AUC 0.500)
