Re-stricture after buccal mucosal graft urethroplasty: a systematic review and meta-analysis.
Synthesis in Acta cirurgica brasileira, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeTo determine risk factors for re-stricture after buccal mucosal graft urethroplasty (BMGU) through a systematic review and meta-analysis.
methodsFollowing PRISMA guidelines, we collected data from PubMed, Scientific Electronic Library Online (SciELO), and Web of Science databases. The eligibility criteria included studies with male patients over 18 years old with urethral stricture recurrence after BMGU.
resultsWe retrieved 646 papers from three electronic databases. Records that did not meet the eligibility criteria and duplicates were excluded, resulting in 14 papers (3,240 patients) that underwent qualitative analysis, from which nine papers were suitable for meta-analysis. The meta-analysis identified diabetes mellitus (relative risk - RR: 1.58 [95% confidence interval - 95%CI 1.02-2.46];p = 0.04), penile/peno-bulbar site (RR: 1.57 [95%CI 1.04-2.37]; p = 0.03), and stricture size higher than 7 cm (RR: 4.13 [95%CI 2.42-7.04]; p 0.00001) as a predictive factor of re-stricture.
conclusionsThese findings may improve understanding the risk factors for this type of urethroplasty and help surgical decisions. For a more effective analysis, larger and better-distributed study groups and cohorts are needed in the future to clarify whether the combination of a previous disease and the urethroplasty etiology may impact a recurrence-free outcome after stricture correction.
