Incidence and Determinants of Repeat Revascularization After Off- and On-Pump Multivessel Coronary Surgery.
Article in Annals of thoracic surgery short reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Coronary artery bypass grafting is an established treatment for multivessel coronary artery disease. However, the occurrence of repeat revascularization over extended follow-up remains clinically relevant. This study aimed to determine the long-term incidence and predictors of repeat revascularization after off-pump and on-pump multivessel coronary artery bypass grafting. Methods: A retrospective cohort of 10,360 patients who underwent multivessel coronary artery bypass grafting between 1996 and 2017 was analyzed. Propensity score matching (1:1, caliper 0.1) was applied to preoperative variables, yielding 4421 matched pairs. Covariate balance was confirmed using standardized mean differences. Repeat revascularization was defined as any postindex percutaneous coronary intervention or redo coronary artery bypass grafting. Survival free from reintervention was evaluated using Kaplan-Meier analysis. Cox proportional hazards models identified factors associated with repeat revascularization. Results: Freedom from repeat revascularization at 20 years was comparable between matched off-pump and on-pump groups (93.2% vs 90.3%; Conclusions: Long-term freedom from repeat revascularization after multivessel coronary artery bypass grafting is high and comparable between off-pump and on-pump coronary artery bypass grafting. Older age and less extensive coronary disease were protective, while prior percutaneous coronary intervention conferred increased risk. These findings may guide preoperative risk stratification and long-term management planning.
