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
This study aimed to evaluate the comparative efficacy and safety of apixaban and rivaroxaban versus vitamin K antagonists (VKAs) in anticoagulation management in a dialysis population. PubMed, Embase, and the Cochrane Library were searched for studies comparing apixaban or rivaroxaban with VKAs in patients with atrial fibrillation (AF) undergoing dialysis. The primary efficacy endpoints included stroke/systemic embolism (SSE) and all-cause mortality. Safety outcomes encompassed major bleeding, intracranial hemorrhage, and gastrointestinal bleeding. Risk ratios (RR) with 95% confidence intervals (CI) were synthesized using random-effects models. The meta-analysis included three randomized controlled trials (RCTs) and eight observational studies. Pooled analyses showed that apixaban and rivaroxaban were associated with lower risks of major bleeding (RR 0.57, 95% CI: 0.51-0.63), gastrointestinal bleeding (RR 0.66, 95% CI: 0.57-0.76), and intracranial hemorrhage (RR 0.54, 95% CI: 0.36-0.83) compared with VKAs. Additionally, apixaban and rivaroxaban were associated with reduced risk of SSE (RR 0.57, 95% CI: 0.46-0.72) and all-cause mortality (RR 0.73, 95% CI:0.63-0.83), although substantial heterogeneity was present. Exploratory dose-stratified analyses suggested both standard- and low-dose apixaban regimens were associated with favorable efficacy and hemostatic safety relative to warfarin. Consistent numerical trends were observed in the RCT-only analysis, though none reached statistical significance owing to limited sample size. In conclusion, apixaban and rivaroxaban are associated with lower risks of bleeding compared with VKAs in patients with AF and ESRD. However, evidence regarding their efficacy in preventing SSE, all-cause mortality and the optimal apixaban dosing regimen remains inconclusive and requires validation in large, dedicated RCTs.
