The mean follow-up time was 8.88 ± 5.1 years for the entire population. Figure 2 shows the Kaplan–Meier survival curves for the 2 unmatched groups. The long-term survival was similar between groups (log-rank test: P = 0.78). Late survival at 1-, 5- and 10-year was similar between groups at 95 vs 91.3%, 86.7 vs 83.5%, and 67.2 vs 68.4% for redo-OPCAB vs redo-CABG respectively. A multivariate logistic regression model indicated body mass index [odds ratio (OR_ 0.93, 95% confidence interval (CI) 0.86–0.99, P = 0.04) and EuroSCORE (OR 1.18, 95% CI 1.06–1.31, P = 0.01) as independent predictors of the composite outcome.
