The published SRR-set includes SRRs based on both mortality within 30 days, henceforth referred to as SRR-30D, and SRRs based on mortality within 24 hours, henceforth referred to as SRR-24H. The investigators will use these SRRs to calculate cICISS and swiICISS for each patient, henceforth referred to as cICISS-30D, cICISS-24H, swiICISS-30D and swiICISS-24H. Finally, the investigators will assess and compare the performance of cICISS-30D and swiICISS-30D in predicting mortality within 30 days and within 24 hours, and repeat this analysis for cICISS-24H and swiICISS-24H.
