Fig 2 Forest plots demonstrating off-pump versus on-pump coronary artery bypass grafting for (A) mid-term mortality (1 < y ≤ 5), and (B) long-term mortality (y > 5). ([author]” = unknown matched/adjusted patient numbers; CI = confidence interval; df = degree of freedom; IV = inverse variance; RCTs = randomized controlled trials; SE = standard error.)

Fig 4 Forest plots demonstrating off-pump versus on-pump coronary artery bypass grafting (CABG) for repeat revascularization with studies representing data as (A) number of events, and (B) hazard ratio. ([author]∧ = data extracted from percentage freedom from event; CI = confidence interval; df = degree of freedom; IV = inverse variance; PCI = primary coronary intervention; RCTs = randomized controlled trials; SE = standard error.)

Fig 5 Risk of bias assessment for (A) randomized controlled trials, and (B) nonrandomized controlled trials. Green (+) indicates criterion was low risk; red (−) indicates criterion was high risk; yellow (?) indicates criterion had an unclear risk.
