3. Fig 2
Forest plot pooling together the duration of hospital stay for both cohorts. The minimally invasive direct coronary artery bypass graft surgery (MIDCAB) group had a significantly longer stay compared with the percutaneous coronary intervention (PCI) cohort (p = 0.001). (CI = confidence interval; SMD = standardized mean difference.)

4. Fig 3
The forest plot shows the pooled results of mortality between the two cohorts, and demonstrates that mortality in the two groups is comparable (A) during early follow-up and (B) at midterm follow-up. (CI = confidence interval; MIDCAB = minimally invasive direct coronary artery bypass graft surgery; PCI = percutaneous coronary intervention; RR = risk ratio.)

Contour-enhanced funnel plot demonstrating absence of publication bias among included studies. (Dark gray area = 0.1 > p > 0.05; medium gray area = 0.05 > p > 0.01; light gray area = p > 0.01.)

Forest plots demonstrating recurrence of angina in the (A) early period and (B) intermediate period. (CI = confidence interval; MIDCAB = minimally invasive direct coronary artery bypass graft surgery; PCI = percutaneous coronary intervention; RR = risk ratio.)

7. Fig 6
Forest plot demonstrates the individual and pooled incidence of myocardial infarction in the minimally invasive direct coronary artery bypass graft surgery (MIDCABG) and percutaneous coronary intervention (PCI) cohorts. The incidence of acute myocardial infarction (AMI) was comparable at (A) early follow-up and (B) and midterm follow-up. (CI = confidence interval; RR = risk ratio.)

8. Fig 7
Forest plot demonstrates the pooled need for reintervention in the (A) early period and (B) intermediate period. (CI = confidence interval; MIDCAB = minimally invasive direct coronary artery bypass graft surgery; PCI = percutaneous coronary intervention; RR = risk ratio.)

9. Fig 8
The forest plot presents the need for target vessel reintervention (TVR [midterm follow-up]) stratified by the type of drug-eluting stent (DES) used. As demonstrated by the lower part of the figure (DES = 1), the risk of reintervention was higher with DES when compared with minimally invasive direct coronary artery bypass graft surgery (MIDCABG). (CI = confidence interval; PCI = percutaneous coronary intervention; RR = risk ratio.)
