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
Arteriovenous fistula (AVF) is the preferred vascular access for hemodialysis in patients with end-stage renal disease (ESRD), yet high rates of primary failure and suboptimal patency remain significant challenges. The choice of anesthetic technique may influence vascular dynamics and AVF outcomes. This study aims to compare the effectiveness of regional anesthesia (RA) versus local anesthesia (LA) on clinical outcomes following AVF creation in adults with ESRD. A systematic review and meta-analysis was conducted in accordance with PRISMA 2020 guidelines. PubMed, Cochrane Library, Scopus, and ClinicalTrials.gov were searched from inception to November 2025. Randomized controlled trials and comparative observational studies evaluating RA versus LA in adult AVF creation were included. Primary outcomes included primary patency, functional patency, and primary failure rate. Secondary outcomes included complications, re-interventions, anesthesia time, and vascular parameters. Risk ratios (RR) and mean differences (MD) with 95% confidence intervals (CI) were pooled using a random-effects model where appropriate. Ten studies involving 1920 patients (RA: 949; LA: 971) were included. RA was associated with significantly higher primary patency (RR = 0.93; 95% CI: 0.87-0.98; p = 0.01) and lower primary failure rates (RR = 1.47; 95% CI: 1.00-2.16; p = 0.05). Complications (RR = 1.49; p = 0.03) and re-interventions (RR = 2.28; p = 0.03) were significantly higher in the LA group. No significant differences were observed in functional patency, anesthesia time, or brachial artery diameter. RA is associated with improved early AVF outcomes, including higher primary patency and reduced failure, complications, and re-interventions, without increasing operative time. These findings suggest that RA may improve early AVF outcomes in selected settings where expertise and resources are available.
