Does Total Arterial Revascularisation Confer a Survival Advantage in Moderate Left Ventricular Dysfunction? A Retrospective Cohort Study of 1866 Patients.

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
objectivesThe optimal conduit strategy for coronary artery bypass grafting (CABG) in patients with moderate left ventricular dysfunction (LVEF 30-49%) remains debated. While total arterial grafting (TAG) has shown benefits in broader populations, its role in this higher-risk subgroup is unclear. This study aimed to compare short-term outcomes and long-term survival between single arterial grafting (SAG) and TAG in patients with moderate LV dysfunction undergoing CABG.
methodsA retrospective analysis of 1866 patients was performed, with 640 patients matched using propensity scores (320 SAG vs. 320 TAG). Preoperative, intraoperative, and postoperative variables were assessed. Survival was evaluated using Kaplan-Meier analysis and Cox regression.
resultsMatched cohorts were well balanced across baseline characteristics. Long-term survival at 10 and 15 years was numerically higher in the TAG group (85.8% and 79.7%) compared to SAG (81.7% and 74.2%), though not statistically significant (log-rank
conclusionTAG is safe and feasible in patients with moderate LV dysfunction undergoing isolated CABG, with comparable short-term outcomes. Although unadjusted analyses suggested improved long-term survival, this difference was not observed after propensity matching or multivariable adjustment, and grafting strategy was not independently associated with mortality.
