Asymptomatic renal granuloma diagnosed 3 years after Bacillus Calmette-Guérin intravesical injection: A case report and a literature review.
Article in IJU case reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Introduction: Intravesical Bacillus Calmette-Guérin immunotherapy is an effective treatment for non-muscle-invasive bladder cancer, which is occasionally associated with side effects and complications. The incidence of significant renal complications after intravesical Bacillus Calmette-Guérin immunotherapy is less than 2%. We report a case of renal granuloma after intravesical Bacillus Calmette-Guérin immunotherapy for bladder cancer, which radiologically resembled a papillary renal cell carcinoma. Case presentation: A 65-year-old man, who had a medical history of urothelial carcinoma and received intravesical Bacillus Calmette-Guérin therapy, was referred to our Urology Department with a right renal tumor. Imaging findings suggested papillary renal cell carcinoma. Robot-assisted partial nephrectomy was performed, and the histopathological examination revealed epithelioid cell granuloma, which were considered to be Bacillus Calmette-Guérin-related renal granuloma. Conclusion: Bacillus Calmette-Guérin-related renal granuloma mimicking papillary renal cell carcinoma have been reported. We should consider the possibility of renal granulomas when encountering image abnormalities for patients treated with intravesical Bacillus Calmette-Guérin therapy.
