Lingual versus buccal mucosal graft for augmentation urethroplasty: a meta-analysis of surgical outcomes and patient-reported donor site morbidity.
Synthesis in International urology and nephrology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
purposeThis study aimed at comparing surgical outcomes and patient-reported donor site morbidity between lingual mucosal graft (LMG) and buccal mucosal graft (BMG) through a meta-analysis of comparative studies.
methodsA systematic literature search was performed in January 2019 including non-randomized comparative studies and randomized controlled trials (RCT). The assessed data included urethroplasty outcomes, complications, and donor site morbidities such as pain, bleeding, swelling, numbness, difficulty speaking, difficulty eating, mouth opening, and difficulty with tongue protrusion.
resultsA total of 632 patients (LMG 323, BMG 309) from 12 comparative studies (four RCTs and eight non-randomized) were included in the meta-analysis. Overall pooled effect estimates revealed no significant difference on reported surgical outcomes and operative stricture-related complications. The LMG group reported a higher proportion of patients with difficulty speaking (RR 6.96, 95% CI 2.04-23.70) and difficulty with tongue protrusion (RR 12.93, 95% CI 3.07-54.51) within 30 days post-op. In comparison, the BMG group had significantly more incidence of early post-procedural donor site swelling (RR 0.39, 95% CI 0.25-0.61) and numbness within 30 days post-op (RR 0.48, 95% CI 0.23-0.97) and 3-6 months (RR 0.52, 95% CI 0.30-0.90) post-op.
conclusionThe evidence suggests no overall significant difference between LMG and BMG with regard to urethroplasty outcomes at 1-year follow-up. While patients undergoing LMG urethroplasty have a higher chance of experiencing difficulty with speech and difficulty with tongue protrusion within 1 month of surgery, the BMG group is more likely to experience early donor site swelling and mouth opening difficulty within 30 days post-op, as well as oral numbness for up to 6 months.
