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
backgroundA meta-analysis is presented of cardiovascular outcome trials (CVOTs) comparing glucagon-like peptide-1 receptor agonists (GLP-1RA) versus placebo on cardiorenal outcomes in patients with type 2 diabetes mellitus (T2DM).
methodsWe did an electronic search up to June 30, 2021, for eligible trials. We did a meta-analysis of available trial data using a random-effects model to calculate overall hazard ratios (HRs) and 95% CI (confidence intervals). We included data from 8 CVOTs and 60,080 patients (72.4% with established cardiovascular disease).
resultsGLP-1RA reduced major cardiovascular events (MACE) by 14% (HR = 0.86, 95% CI 0.79-0.94, P = 0.006) with a non-significant heterogeneity between subgroups of patients with and without cardiovascular disease (P = 0.127). GLP-1RA also reduced the risk of cardiovascular death by 13% (P = 0.016), nonfatal stroke by 16% (P = 0.007), hospitalization for heart failure by 10% (P = 0.023), all-cause mortality by 12% (P = 0.012), and the broad composite kidney outcome by 17% (P = 0.012), which was driven by a reduction in macroalbuminuria only (HR = 0.74, 0.67-0.82, P < 0.001).
conclusionsGLP-1RA have moderate benefits on MACE, and also reduce hospitalization for heart failure and all-cause mortality; they also have robust benefits on reducing the incidence of macroalbuminuria.
