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
backgroundHypospadias is a common congenital anomaly characterized by the displacement of the urethral opening to the ventral side of the penis. Surgical correction is often necessary for functional and psychological reasons. The etiology involves genetic and environmental factors, and chordee, a downward curvature of the penis, is a common complication. Proteins such as fibulin-1, elastin, matrix metalloproteinase-1, basic fibroblast growth factor, and α-smooth muscle actin play roles in hypospadias development.
objectiveThe study's aim is to investigate the differences in messenger RNA (mRNA) expression of fibulin-1, elastin, matrix metalloproteinase-1, basic fibroblast growth factor, and α-smooth muscle actin between the ventral and dorsal tunica dartos in patients with hypospadias and chordee.
methodsThis prospective cohort study aims to investigate differences in mRNA expression of the abovementioned proteins between the ventral and dorsal tunica dartos in patients with hypospadias and chordee. Ethics approval has been obtained, and consent from parents will be obtained before data collection. Eligible participants are aged 6-18 months, diagnosed with hypospadias and chordee, and planned for urethroplasty. Tissue samples will be collected from both aspects of the tunica dartos and analyzed using real-time quantitative reverse transcription-polymerase chain reaction. Data analysis will involve statistical tests and normalization of housekeeping genes.
resultsThis study is at the protocol development stage. A pilot study regarding its feasibility has been ongoing as of August 2023. The study results are expected to be available by the end of 2024.
conclusionsThe study of mRNA expressions of various proteins in the tunica dartos of patients with hypospadias and chordee is expected to improve the understanding and expand the knowledge of the pathophysiology of hypospadias and chordee.
