Sex-specific differences in recurrence and progression following cytostatic intravesical chemotherapy for non-muscle invasive urothelial bladder cancer (NMIBC).
Synthesis in Journal of cancer research and clinical oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis that pooled it.
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
purposeTo systematically analyze gender-specific differences in recurrence-free survival (RFS), progression-free survival (PFS), cancer-specific survival (CSS), and overall survival (OS) as well as adverse events and quality of Life (QoL) as secondary aims in NMIBC patients undergoing cytostatic intravesical chemotherapy.
methodsA systematic review and meta-analysis were conducted on studies published between 1976 and 2024, following PRISMA guidelines. MEDLINE, Embase and Cochrane Library were used as literature sources. No restrictions were made concerning language, study region or publication type. Data from 12 studies encompassing 1,527 patients were analyzed. Outcomes were assessed using random-effects models, with gender as a primary variable of interest. A risk of bias assessment was done using the ROBINS-I tool or RoB2 as appropriate.
resultsThe pooled analysis demonstrated no statistically significant gender-specific differences in RFS (HR = 1.0625, 95% CI 0.8094-1.0526) or PFS (HR = 1.0861, 95% CI 0.7038-1.6760). Data on CSS and OS were insufficient for meaningful conclusions. Two included studies analyzed in univariate or multivariate regression gender as risk factor for recurrence or progression, but gender was not a significant risk factor. Adverse events and QoL outcomes were notably underreported, with no gender-specific data available.
conclusionsWhile this study found no significant gender-based differences in NMIBC outcomes following intravesical chemotherapy, the findings are limited by the small number of studies, underrepresentation of women, and inconsistent reporting of critical outcomes. Future research should prioritize gender-focused analyses and explore the molecular and genetic basis of potential differences to inform precision medicine and equitable care.
