Tunica Vaginalis Versus Dartos as Interposition Soft Tissue in Hypospadias Repair: A Systematic Review and Meta-analysis.
Review in Journal of Indian Association of Pediatric Surgeons. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Hypospadias is one of the most common congenital anomalies of the male urethra, with urethrocutaneous fistula (UCF) being its most common postoperative complication. An interposition tissue layer is often used between the neourethra and skin to reduce the incidence of UCF. Dartos flap (DF) has traditionally been preferred, whereas the tunica vaginalis flap (TVF) has gained popularity for its robust vascularity. This systematic review and meta-analysis aimed to compare outcomes of TVF versus DF in primary hypospadias repair (TIP). PRISMA guidelines were followed. Randomized controlled trials (RCTs) comparing TVF and DF as interposition layers were identified through MEDLINE, Embase, Scopus, CENTRAL, trial registries, and Google Scholar. Inclusion criteria comprised children undergoing TIP with postoperative outcomes as variables. Risk of bias was assessed using the Cochrane RoB2 tool. Pooled analyses were performed using RevMan web. A fragility index (FI) was calculated for the primary outcome. Four RCTs, including 209 patients (TVF: 97, DF: 112), were included for analysis. UCF occurred in 9.28% in the TVF group versus 30.36% in the DF group. Pooled analysis favored TVF (risk ratio: 0.37; 95% confidence interval: 0.19-0.70,
