From: Clinical results after hybrid coronary revascularization with totally endoscopic coronary surgery
Estimated survival (Kaplan–Meier) of major adverse cardiac and cerebrovascular events (MACCE) and all-cause mortality in unmatched (a, b) and propensity score matched patients (c, d). Unmatched endoscopic coronary artery bypass grafting (Endo-CABG): n = 244; matched Endo-CABG: n = 103; Hybrid: n = 103. A p value of < 0.05 is considered statistically significant
