Androgen receptor expression in the foreskin of children born with hypospadias: a systematic review.
Synthesis in Pediatric surgery international, 2025. 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 a congenital malformation of the penis affecting 1 in every 250 male births. Measurement of androgen receptor (AR) levels in the foreskin has been used to elucidate the role of this receptor in the hypospadias aetiology. This review evaluates the extent of immunohistochemical AR expression in the foreskin of boys with hypospadias, compared to their unaffected counterparts. Several databases (MEDLINE, Embase, and The Cochrane library) were searched to find studies relevant to our research question. From 657 studies, 24 underwent full-text review, and 8 were included in a narrative synthesis analysis of the findings reported by the literature. Four studies reported significantly increased quantified AR expression in hypospadias (p < 0.05), while three described significantly decreased expression (p < 0.013), and one reported no significant difference between groups. Furthermore, AR expression was found to be higher in the stroma of the foreskin than the epithelium. No clear consensus has been established regarding the relationship between AR expression and hypospadias in the literature. This may be due to variability in the age of participants included in the study, or additional factors such as genetic conditions, highlighting the need for a standard approach to investigation.
