Fig 2 The pooled result demonstrates that patients undergoing off-pump coronary artery bypass grafting (OPCABG) had a significantly fewer number of grafts than did patients in the on-pump CABG (ONCABG) cohort (mean difference, –0.52 [–0.83 to –0.20]). (CI = confidence interval; SD = standard deviation.)

Fig 4 (A) Funnel plot demonstrates publication bias for the analysis of stroke (p = 0.01). (B) The adjusted Forest plot demonstrates that off-pump coronary artery bypass grafting (OPCABG) has a lower stroke risk than on-pump CABG (ONCABG). (RR = risk ratio; seTE = standard error for treatment estimate; TE = treatment estimate.)

Fig 5 (A) Forest plot for respiratory failure demonstrates that off-pump coronary artery bypass grafting (OPCABG) is better than on-pump CABG (ONCABG). (B) Cumulative meta-analysis demonstrates that the resultant heterogeneity (I2 ) is caused by adding Cavallaro and colleagues to the pooled result. (RR = risk ratio.)

Fig 6 Forest plot for postoperative atrial fibrillation demonstrates that rates are comparable in both cohorts (p = 0.27). The Annals of Thoracic Surgery 2015 99, 1568-1575DOI: (10.1016/j.athoracsur.2014.12.057) Copyright © 2015 The Society of Thoracic Surgeons Terms and Conditions
