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
Background: The transverse preputial island flap (TPIF) procedure remains one of the classic single-stage procedures for severe hypospadias repairs. The incidence of postoperative complications remained high. This study aims to describe a modified urethral anastomosis technique during the TPIF procedure for severe hypospadias repairs and report its outcomes. Methods: Data were collected retrospectively from consecutive patients who underwent the TPIF procedure by the same pediatric urologist between January 2018 and June 2023. Collected information included age at surgery, operative details, and outcomes at follow-up. Wide-based oblique anastomosis (WOA) technique was used as a modified urethral anastomosis in all cases. In brief, the dorsal edge of anastomosis was breadthwise anchored to the corpus cavernosum with 4-5 stitches, forming a spade-shaped anastomotic surface. Results: A total of 72 patients were included in the study. The location of the corpus spongiosum division was penile in 27 patients (37.5%) and proximal in 45 patients (62.5%). The median glans width was 13 mm (range, 6-30 mm). The median ventral curvature after degloving was 45° (range, 30-150°). At a median follow-up of 4.1 years, complications occurred in 15 patients (20.8%), including nine cases of fistula, seven cases of urethral diverticulum and two cases of meatal stenosis. No cases of urethral stricture (US), urethral dehiscence, or ventral curvature occurred. Subsequent reoperations for diverticulum repairs showed that the dorsal side of the anastomosis was extensively fixed to the corpus cavernosum, forming a wide-based, spacious lumen. Conclusions: WOA technique is straightforward and effective, especially in the prevention of postoperative US.
