Two-year survival stratified by EuroSMR score risk prediction (validation cohort) the performance of the EuroSMR risk score for survival/mortality prediction was proved in the validation cohort. In this cohort, approximately one-quarter of patients were identified as high-risk patients for mortality. The respective hazard ratio for mortality at 1-year in this group was 4.5 when compared with the remaining patients at lower risk.
