Preoperative topical estrogen application in the management of hypospadias: a systematic review.
Synthesis in Pediatric surgery international, 2024. 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
Local estrogen therapy has been explored as an alternative to conventional testosterone therapy in children requiring urethroplasty for hypospadias. Our objective is to evaluate if preoperative estrogen stimulation reduces post-urethroplasty complications and enhances penile dimensions. A systematic search was conducted on various databases, selecting only randomized controlled trials (RCTs) that tested estrogen on hypospadias patients under 18 years. Articles underwent sorting following PRISMA guidelines and bias risk was assessed using the JBI clinical appraisal tool for RCTs. Out of 607 screened records, 10 underwent full-text review, and 4 randomized controlled trials (RCTs) were selected for analysis. The total patient cohort across studies was 387 with 174 in the estrogen group. All studies utilized topical estrogen, but in different formulations and timings. Prudence is necessary for interpreting results due to variations in formulation, timing, and hypospadias type across studies. Limited by a small number of studies and outcome presentation non-uniformity, the review suggests no change in penile dimensions or postoperative complications with topical estrogen. Further research is needed to explore wound-healing properties of estrogen in hypospadias through animal and human studies.Registration and protocol: Registered in Prospero CRD42024502183.
