Hazard ratios within strata of age and the Simplified Acute Physiology Score (SAPS), comparing the survival probability in the lowest to the highest quartiles of our proposed optimized summary comorbidity measure. The linear predictors from model H (see Additional file 1: eTable S8 for description), but excluding age and sex from the model, were used as a summary measure of comorbidity for each individual. Hazard ratios could not be estimated for the lowest SAPS strata
