1 · What the graph read from 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.

2 · The registry

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 to compare the efficacy of modified transverse preputial island flap (TPIF) repair with the traditional TPIF procedure and Byar's two-stage procedure in proximal hypospadias repair, especially in the postoperative urethral stricture incidence rates. MATERIALS AND

methodsPatients admitted for proximal hypospadias treated with modified TPIF repair, the traditional TPIF procedure, or Byar's two-stage procedure at our institution from 2017 to 2021 were identified, and the incidence of postoperative complications among them was compared.

resultsIn total, 142 patients were included (modified TPIF group, 43; traditional TPIF group, 37; and Byar's two-stage group, 62). The length of the neourethra was 4.21 ± 0.63 cm in the modified TPIF group, 4.18 ± 0.71 cm in the traditional TPIF group, and 4.20 ± 0.68 cm in the Byar's two-stage group. The rate of urethral stricture in the modified TPIF group (two cases, 4.65%) was significantly lower than that in the traditional TPIF group (four cases, 10.81%) (P = 0.008). Seven (16.28%) cases of urethrocutaneous fistula occurred in the modified TPIF group, six (16.22%) in the traditional TPIF group, and eight (12.90%) in the two-stage group. Additionally, one case (2.33%) of urethral diverticulum occurred in the modified TPIF group, one (2.70%) in the traditional TPIF group, and three (4.84%) in Byar's two-stage group.

conclusionsModified TPIF repair can ensure a wedge anastomosis between the proximal urethral meatus and the neourethra, provide support and blood supply for the neourethra. Furthermore, it extended the urethral plate width at the anastomosis and urethral meatus, effectively reducing the incidence of urethral strictures.
