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
purposeThe concept of interposing double dorsal preputial flaps to cover the urethroplasty was introduced in 2005 to reduce the risk of urethrocutaneous fistula (UCF). Our study aims to compare the postoperative outcomes of urethroplasty for distal hypospadias between two groups: one receiving single preputial flap coverage and another receiving double flap coverage. MATERIALS AND
methodsWe conducted a retrospective analysis study of boys with primary distal hypospadias who underwent surgery by the same experienced surgeon, at our department between 2010 and 2021. The study population was divided into two groups: Group A, which underwent urethroplasty coverage with single dorsal preputial flap, and Group B, which underwent coverage with double flap. Postoperative complications were compared between the two groups.
resultsWe collected 105 cases, comprising 51 in Group A and 54 cases in Group B. The mean age at surgery was 29 months in Group A and 24 months in Group B. Post-operative follow-up period ranged from 6 months to 8 years. Functional and cosmetic outcomes were judged excellent in 88.7%. Only 10 boys experienced complications requiring reoperation. UCF occurred in 5 patients from Group A, while no cases were reported in Group B (p = 0.024). Meatal stenosis was identified in three patients in Group A and in two patients in Group B (p = 1). No other complications, such as glans dehiscence or penile torsion, were noted.
conclusionDouble dorsal dartos flap is an effective method for covering the new urethra and can be recommended in the treatment of patients with virgin distal hypospadias.
