Meta-analysis of the composite endpoint of death, myocardial infarction (MI), stroke and repeat revascularization (RR). Panel a Forest plot and summary effect of the difference in the incidence of the composite endpoint of death, MI, stroke and RR, showing a significantly lower incidence in the CABG arm. Panel b Subgroup analysis showing no difference between CABG and PCI within the lower tertiles of the SYNTAX Score (SYNTAX 0–32), but better performance of CABG within the highest tertile (SYNTAX >33)
