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

introductionHerein, we compared surgical outcome of dorsal shortening (DS) vs. ventral lengthening (VL) for correcting congenital ventral curvatures.

methodsA systematic literature search was performed in September 2021 using the PubMed, EMBASE, Scopus, CENTRAL, ProQuest, and Clinicaltrials.gov databases. Comparative studies were identified and evaluated according to Cochrane Collaboration recommendations. Assessed outcomes included success and complication rates, which were extrapolated for the respective odds ratios (OR) with 95% confidence intervals (CIs). Subgroup analyses were performed according to congenital curvature, with or without severe hypospadias or recurrent curvatures (PROSPERO: CRD42021276193).

resultsBased on pooled effect estimates from 12 studies with 430 (DS 253, VL 177) cases of ventral curvature repair, VL rendered a better success rate for curvature correction (OR 4.20, 95% CI 2.11, 8.33) than DS, with comparable composite surgical complication rates (OR 0.77, 95% CI 0.27, 2.18). Subgroup analysis showed that the success rate remained significantly better for VL among patients with associated severe hypospadias (OR 3.59, 95% CI 1.25, 10.26) and recurrent penile curvatures (OR 5.70, 95% CI 1.69, 19.21) but not among those with congenital curvature without hypospadias or those with mild hypospadias (OR 2.99, 95% CI 0.32, 27.57).

conclusionsFor congenital curvature associated with severe hypospadias and recurrent curvatures, VL renders a modestly better success rate; however, careful selection of patients is key for best outcome.
