Risk factors for failed urethrocutaneous fistula repair after transverse preputial island flap urethroplasty in pediatric hypospadias.
Article in International urology and nephrology, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
objectivesWe review our experience in urethrocutaneous fistula (UCF) repair after transverse preputial island flap urethroplasty (Duckett) in pediatric hypospadias to investigate the risk factors for unsuccessful outcome.
methodsTwo hundred and nineteen UCFs repairs conducted in our center from January 2015 to December 2016 after Duckett technique were retrospectively reviewed and 182 had a follow-up for more than 6 months. The age of patients, size, localization and numbers of UCFs, interval time of two operations, length of neourethra, times of UCFs repairs, complications other than UCFs, hospital of primary surgery and postoperative infection were analyzed as potential risk factors. Stratified analysis and assessment of additive interaction were performed to have a better understanding of the relation between the risk factors. Logistic regression analysis was used for multivariate analysis.
resultsUCF repairs were succeeded in 121 (66.5%) and failed in 61 (33.5%) at first operation. In the univariate analysis, size and numbers of UCFs (P = 0.01 and P = 0.035, respectively), interval time of two operations (P = 0.042) and hospital of primary surgery (P = 0.02) were statistically related with the outcome. In the multivariate analysis, UCF ≥ 2 (OR 2.71, 95%, CI 1.095-6.692, P = 0.031), size ≥ 2 mm (OR 2.45, 95% CI 1.267-4.757, P = 0.08) and primary surgery not at our hospital (OR 2.21, 95% CI 1.094-4.126, P = 0.026) were identified as independent risk factors for unsuccessful outcome. In the stratified analysis, multiplicative interaction between the 3 risk factors was not found.
conclusionsOur study suggested that UCF repairs after transverse preputial island flap urethroplasty were easier to fail if the UCF was ≥ 2 mm, the numbers of UCFs was ≥ 2, or the surgeon had less experience. The age of patients, site of UCFs, interval time of two operations, length of neourethra, times of UCFs repairs, complications other than UCF and postoperative infection were not significantly related to the success rate of UCF repair.
