What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesTo assess short-term outcomes of coronary artery bypass grafting (CABG) with adjunct coronary endarterectomy (CE) compared with isolated bypass grafting, and to synthesize available confounder-adjusted effect estimates.
methodsWe conducted a systematic review and meta-analysis following PRISMA guidelines. MEDLINE, Embase, and CENTRAL were searched from January 2000 to June 2025. Eligible studies compared adult patients undergoing CABG with CE versus isolated CABG. Two reviewers independently screened studies, extracted data, and assessed quality. Random-effects meta-analysis was performed. The primary outcome was 30-day or in-hospital mortality.
resultsSixteen studies (119 458 patients) were included. CABG with CE was associated with higher mortality (RR 1.84, 95% CI 1.65-2.04). Pooling adjusted odds ratios from 3 studies yielded OR 1.76 (95% CI 1.55-2.00), with 2 of 3 individual estimates not reaching significance. Secondary outcomes showed increased risks of perioperative myocardial infarction (RR 1.99, 95% CI 1.29-3.07), stroke (RR 1.37, 95% CI 1.08-1.75), renal failure (RR 1.62, 95% CI 1.44-1.82), and intra-aortic balloon pump use (RR 1.96, 95% CI 1.41-2.70). Sensitivity analyses confirmed consistency across all the subgroups.
conclusionsCABG with CE is associated with higher short-term mortality and morbidity compared with isolated bypass grafting; however, confounder-adjusted analyses suggest this excess risk is partly attributable to greater baseline disease severity rather than an independent procedural effect. The scarcity of data and absence of randomized evidence preclude definitive causal conclusions. These findings provide benchmarking data for counselling when endarterectomy is necessary to achieve complete revascularization.
