Sex as modifier of survival in patients with advanced urothelial cancer treated with pembrolizumab.
Observational study in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Gender- and sex-based disparities in response to immune-checkpoint inhibitors (ICI) has been reported in a variety of tumor types. Women have different anatomy with recurrent urinary tract infections, a different sex hormonal profile, and intrinsic differences in local and systemic immune systems and urobiome composition. Existing literature data in a pan-cancer context reveal contradictory results, and real-world evidence in urothelial carcinoma (UC) is lacking. This was a real-world, multicenter, international, observational study to determine the sex effects on the clinical outcomes in metastatic urothelial carcinoma (mUC) patients progressing or recurring after platinum-based therapy and treated with pembrolizumab as a part of routine clinical care. A total of 1039 patients, treated from January 1st, 2016 to December 31st, 2023 in 68 cancer centers were included. Our data showed that women with metastatic urothelial carcinoma treated with pembrolizumab had shorter OS than men, with a 13% advantage in the 5-year OS rate for male patients. A deeper understanding of these results may inform sex-stratification in future prospective clinical trials and help develop strategies to reduce the magnitude of the sex disparities observed in urothelial cancer outcomes.
