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
purposeLong-segment urethral strictures following hypospadias repair (LUSPH) represent a formidable reconstructive challenge. Few techniques simultaneously achieve durable stricture resolution while preserving the distal urethral meatus. This study evaluates the efficacy, safety, and patient-reported outcomes of staged buried oral mucosal strip urethroplasty for LUSPH. PATIENTS AND
methodsA retrospective analysis was conducted on patients undergoing this procedure between June 2016 and June 2024. Stage one involved inlay of an oral mucosal graft. In the second stage, the healed composite mucosal strip was tubularized using penile fascial flap. Outcomes assessed included maximum flow rate (Qmax), patient-reported outcome measures (USS-PROM, QoL-PROM, IIEF-5), surgical success (defined as unobstructed voiding without intervention, Qmax >15 mL/s, and absence of major complications), and complications.
resultsSixty-one patients were enrolled, with a mean age of 29.8 ± 9.1 years and mean stricture length of 4.7 ± 0.7 cm. Ultimately, 51 patients (83.6%) achieved unobstructed voiding meeting the definition of surgical success. The mean Qmax at 1-year postoperatively was 18.5 ± 4.3 mL/s. From preoperatively to 1-year postoperatively, USS-PROM scores significantly decreased from 21.0 ± 2.0 to 6.6 ± 2.2 (P < 0.001), while QoL-PROM scores significantly improved from 46.6 ± 6.7 to 87.2 ± 8.2 (P < 0.001). IIEF-5 scores showed no significant change. Finally, 54 patients (88.5%) maintained a meatus positioned above the coronal sulcus.
conclusionsIn this single-center retrospective cohort, staged buried oral mucosal strip urethroplasty demonstrated favorable mid-term efficacy and safety for LUSPH.
