Efficacy and Safety of Ultrasound-Guided Nerve Block Versus Local Anesthesia for Arteriovenous Fistula Angioplasty: A Systematic Review and Meta-Analysis.
Review in Health science reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Background and Aims: Severe intra-procedural pain commonly complicates percutaneous transluminal angioplasty (PTA) for dysfunctional arteriovenous fistulas (AVFs), undermining patient cooperation and potentially increasing the need for sedative medications. This systematic review and meta-analysis aimed to evaluate the analgesic efficacy, safety, and clinical performance of ultrasound-guided nerve block (UGNB) versus local anesthesia (LA) in adult patients undergoing AVF PTA. Methods: We searched PubMed, Embase, Scopus, the Cochrane Library, and Web of Science for eligible randomized controlled trials and cohort studies published up to September 1, 2025. The primary outcome was intra-procedural pain rated using VAS or NRS on a 0-10 scale. The secondary outcome was overall safety, assessed using the available complication-free outcome. Random-effects models were used for pooled analyses. Heterogeneity was explored using Galbraith plots and leave-one-out analyses. Funnel plots were generated for exploratory visualization because fewer than 10 studies were included. Subgroup analyses were performed according to UGNB subtype, and an exploratory subgroup analysis was additionally conducted by study design. Results: Four eligible studies, including 664 participants from East Asia, were included in the quantitative synthesis. In the primary pain analysis, UGNB was associated with a marked reduction in intra-procedural pain relative to LA (SMD -2.85, 95% CI -4.70 to -1.01; Conclusion: UGNB was associated with superior analgesia without a clear increase in adverse events during AVF PTA. Current evidence does not establish a statistically significant difference between BPB and SCNB, and the SCNB subgroup should be interpreted cautiously because of substantial heterogeneity. Larger multicenter trials are needed to compare block techniques directly and to evaluate recovery, patency, and cost-effectiveness.
