Undescended testis: an epidemiological study from a single institution.
Article in Revista paulista de pediatria : orgao oficial da Sociedade de Pediatria de Sao Paulo, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
objectiveThe aim of this study was to assess the referral and treatment timelines for patients with undescended testis treated in the Pediatric Surgery Division at Escola Paulista de Medicina/UNIFESP.
methodsRetrospective review of patients treated for undescended testis at a tertiary care institution from 1992 to 2021. Ethical approval was granted by the institutional ethics committee. Data collected included patients' demographics and clinical characteristics, referral age, age at orchidopexy, testis laterality and position prior to surgery, and duration of postoperative follow-up. A descriptive analysis was performed for each variable, excluding patients with incomplete medical records.
resultsIn the cohort of 350 patients with undescended testis, 72.6% had unilateral and 27.4% bilateral presentations; and 8% of the patients had differences in sex development. Ultrasound was requested in 19.5% of cases. The average age at referral was 47.3 standard deviation (±) 41.6 months, with 72.5% referred after 18 months. Among 131 orchidopexy procedures, 12.8% were performed before 12 months of age, 15.9% until 18 months, and the majority after 60 months. Of the 120 patients who underwent surgery, only 78.3% had postoperative follow-up data, and 52.1% lost follow-up. The average follow-up period was 23.1±26.20 months.
conclusionsThe average age at diagnosis and treatment of undescended testis was higher than recommended by international guidelines, indicating the need for enhanced medical and non-medical community referral practices.
