Contemporary outcomes in non-muscle-invasive bladder cancer: a large European multicentre study.
Article in BJU international, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
objectiveTo report real-world rates of non-muscle-invasive bladder cancer (NMIBC) recurrence and progression within a European multicentre cohort with detailed information on intravesical instillation courses, as contemporary data on oncological outcomes in NMIBC are limited. PATIENTS AND
methodsA total of 1918 patients with NMIBC treated with transurethral resection of bladder tumour (TURBT) were retrospectively identified from six tertiary-referral European centres (2015-2022). Patients were stratified according to European Association of Urology 2021 criteria into low- (LR), intermediate- (IR), high- (HR) and very high-risk (VHR) categories. Cumulative incidence plots and multivariable competing risks regression models addressing 5-year rates of high-grade (HG) recurrence and progression were fitted. Sensitivity analyses focused on patients receiving intravesical instillations and tested for the effect of adequate course (Bacillus Calmette-Guérin: five or more induction + two or more maintenance instillations; mitomycin C: complete induction + ≥11 maintenance instillations).
resultsOf all NMIBC patients identified, 467 (24.3%) were LR vs 582 (30.3%) IR vs 739 (38.5%) HR vs 130 (6.8%) VHR. The median (interquartile range) follow-up after TURBT was 26 (12-46) months. The 5-year HG recurrence rates were 7.2% in LR vs 17.3% in IR vs 26.7% in HR vs 30.9% in VHR patients, resulting in a three-, five- and seven-fold higher risk of IR, HR and VHR, respectively, relative to LR (all P < 0.001). The 5-year progression rates were 3.9% in LR vs 5.2% in IR vs 13.6% in HR vs 31.6% in VHR patients, resulting in a six- and nine-fold higher risk for HR and VHR, respectively, relative to LR (all P < 0.001). In all, 1001 (52.2%) patients underwent intravesical instillations. Those receiving adequate instillation course (244/1001 [24.3%]) had lower HG-recurrence (hazard ratio 0.3, P < 0.001) and progression (hazard ratio 0.2, P = 0.001) risk.
conclusionsPatients with HR/VHR NMIBC face significantly higher HG recurrence and progression risks. While tailored treatment strategies are needed, adherence to adequate instillation course remains crucial for optimising oncological outcomes.
