A 27-Year Comparative Analysis of Off-Pump and On-Pump Coronary Artery Bypass Grafting in Octogenarians.

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: Octogenarians are deemed a high-risk patient population with increased postoperative morbidity and mortality after conventional coronary artery bypass grafting with cardiopulmonary bypass. In such patients, reducing the invasiveness of the surgical procedure by avoiding cardiopulmonary bypass may improve outcomes. This study investigates the in-hospital outcomes, 30-day mortality, and long-term survival rates of off-pump coronary artery bypass (OPCAB) vs on-pump coronary artery bypass (ONCAB) in octogenarians and identifies significant preoperative predictors of long-term mortality. Methods: This retrospective cohort study included octogenarian patients who underwent either OPCAB or ONCAB, between January 1996 and September 2023, at our institution. In-hospital outcomes, 30-day mortality, and long-term survival during 20 years were compared between the groups. Propensity score matching was used to adjust for baseline differences. Statistical analyses included univariate and multivariate Cox regression analyses and Kaplan-Meier survival estimates. Results: Of 711 patients, 245 pairs were matched. Unmatched analysis showed that OPCAB had lower tracheostomy rates (1.5% vs 4.7%, Conclusions: OPCAB may reduce short-term mortality in octogenarians while providing comparable long-term survival to ONCAB. Surgical strategy should be individualized on the basis of preoperative risk profiles.
