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
introduction and hypothesisThis study aims to systematically compare the efficacy of dorsal onlay buccal mucosal graft urethroplasty (BMGU) and ventral onlay BMGU in the treatment of female urethral stricture (FUS), evaluating key outcomes such as success rate, postoperative maximum urinary flow rate (Qmax), postoperative post-void residual volume (PVR), and postoperative American Urological Association (AUA) score.
methodsA literature search was conducted across PubMed, Embase, Web of Science, and Cochrane Library databases. Statistical analysis was performed using Review Manager 5.3 software and Stata version 18.0, and a random-effects model was applied to analyze data with significant heterogeneity.
resultsFive studies met the inclusion criteria, involving a total of 319 patients (112 with dorsal onlay and 207 with ventral onlay). The pooled analysis showed no significant difference between the two surgical approaches in terms of success rate (relative risk [RR] 1.00; 95% confidence interval [CI] 0.91, 1.10; p = 0.95). At 6 months postoperatively, Qmax (mean difference [MD] -0.88; 95% CI -2.21, 0.46; p = 0.20), PVR (MD 0.74; 95% CI -3.04, 4.52; p = 0.70), and AUA score (MD -0.54; 95% CI -1.24, 0.15; p = 0.13) were similar between the dorsal and ventral groups.
conclusionsDorsal onlay BMGU and ventral onlay BMGU show similar efficacy in treating FUS. The choice of surgical approach should be based on individual patient factors, such as the location, severity of stricture, and history of prior treatments.
