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
purposeTo identify and evaluate cardiovascular outcome trials for glucagon-like peptide-1 receptor agonists (GLP1RAs) in various patient populations, including those with or without type 2 diabetes (T2D). SUMMARY: A systematic search of MEDLINE identified 12 cardiovascular outcome-based randomized controlled trials: 10 in patients with T2D, one in patients with overweight/obesity and atherosclerotic cardiovascular disease (ASCVD) but not T2D, and one in patients with obesity and heart failure with preserved ejection fraction (HFpEF). Most trials had a low risk of bias. The GLP1RA was administered as a weekly subcutaneous injection in 8 trials, and 2 trials used once-daily oral semaglutide. Follow-up ranged from 1.2 to 5.4 years. GLP1RA therapy showed a consistent reduction in major adverse cardiovascular events (MACE) in patients with T2D. The effect on cardiovascular and all-cause death was less certain. Individually, only liraglutide demonstrated a reduction in MACE, cardiovascular death, and all-cause death. In patients with overweight/obesity and ASCVD (but without T2D), weekly subcutaneous semaglutide lowered the risk of MACE but not cardiovascular death. In patients with obesity and HFpEF (with or without T2D), tirzepatide lowered the occurrence of the composite endpoint of adverse heart failure events and cardiovascular death. Discontinuation of GLP1RA therapy due to gastrointestinal adverse events was common across the trials.
conclusionThese data support the use of GLP1RAs to lower MACE in patients with T2D. A cardiovascular benefit with GLP1RA therapy was also observed in 2 additional patient populations: those with overweight/obesity and ASCVD but without T2D and those with obesity and HFpEF with or without T2D.
