Based on algorithm # 8, hazard ratios and 95% confidence intervals for the primary outcome, death or cardiac hospitalization (A), and for the secondary outcome, all-cause mortality (B), calculated for the tertile groups of left ventricular end-diastolic volume index, end-systolic volume index, and ejection fraction. (C) Hazard ratios and 95% confidence intervals for the primary outcome of the STICH trial, death or cardiac hospitalization, and for the secondary outcome, all-cause mortality, calculated for the three groups of LVESVI (≤60, 60–90, and ≥90 mL/m²). The actual numbers of events in coronary artery bypass grafting and CABG + SVR groups are shown for the above groups of left ventricular end-diastolic volume index, end-systolic volume index, and ejection fraction based on algorithm #8 in Supplementary material online, Table S3.
