Low-grade non-muscle-invasive urothelial carcinoma of the bladder in a 16-year-old boy with UGT1A1 polymorphism and Gilbert's syndrome: A case report.
Article in Urology case reports, 2026. 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
Bladder cancer in the pediatric and adolescent population is exceedingly rare.Genetic susceptibility factors, including polymorphisms in phase II detoxifying enzymes, may play a role in early tumorigenesis. We report the case of a 16-year-old male with recurrent gross hematuria, ultimately diagnosed with low-grade papillary urothelial carcinoma following transurethral resection of bladder tumor (TURBT). Genetic analysis identified a UGT1A1 polymorphism associated with reduced enzymatic activity, a known determinant of impaired detoxification, and the patient had coexistent Gilbert's syndrome. We discuss clinical presentation, management, and the potential correlation between UGT1A1 alterations, Gilbert's syndrome, environmental carcinogen exposure, and bladder carcinogenesis.
