Observed mortality according to various risk assessment strategies. Mortality analysis by Kaplan–Meier (KM) modeling at baseline (a) and first follow-up (b). At baseline seven different risk-stratification approaches (COMPERA, SPAHR, FPHR3p, FPHR4p, mRASP, REVEAL 2.0 and REVEAL Lite 2) are depicted. At the first follow-up, KM modeling according to the FPHR3p and mRASP model is shown. The colour of KM curves is matched to score strata. Initial patient numbers in each stratum are presented for each score. Statistical significance was assessed with Wilcoxon test. For COMPERA, SPAHR, and mRASP three risk strata (low, int. = intermediate and high) are presented, for the FPHR models number of met low-risk criteria is shown
