Patients with Metastatic or Locally Advanced Bladder Cancer Not Undergoing Systemic Oncological Treatment-Characteristics and Long-Term Outcome in a Single-Center Danish Cohort.
Article in Cancers, 2025. 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
backgroundA subset of patients with locally advanced or metastatic bladder cancer (la/mBC) do not receive systemic oncological treatment. The reasons for refraining from systemic treatment are poorly investigated, as are the characteristics of patients who turn out to be long-term survivors despite lack of treatment.
methodsThis retrospective observational cohort study included patients with registration compatible with la/mBC who did not undergo systemic treatment. They were seen at a single tertiary university hospital covering one of 5 Danish regions in the study period from 1 January 2012 until 31 December 2022. Patients were identified through a coding system, and detailed patient information was obtained in the electronic medical records.
resultsThe initial study population consisted of 472 patients registered with la/mBC according to codes in the patient registries but with no registration of systemic oncological treatment. Out of the total cohort, 159 patients were registered correctly, while the rest of the population were excluded due to misclassification, as 10.8% did not have la/mBC and 55.5% had received oncological treatment. Among correctly registered patients, the median overall survival was 2.6 months (95% CI 0.26; 4.94) from being diagnosed with la/mBC. The most common reasons for lack of treatment were poor general condition (74.2%), patient preference (19.5%), and poor renal function (11.9%).
conclusionsOur study found that a significant amount of patients in a cohort of suspected la/mBC not undergoing treatment either received oncological treatment or did not have la/mBC, demonstrating a misclassification in the system. This should be taken into consideration when evaluating data about survival time for this patient group. The poorest survival of untreated la/mBC is associated with a high tumor burden and specifically liver metastasis.
