Socioeconomic disparities and bladder cancer stage at diagnosis: a statewide cohort analysis.
Article in JNCI cancer spectrum, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundBladder cancer is the ninth most common cancer worldwide. Despite its prevalence, large-scale studies on the relationship between socioeconomic disparities and disease stage at presentation are lacking. This study examines the association between the Area Deprivation Index (ADI), a robust measure of socioeconomic status, and stage at diagnosis among bladder cancer patients.
methodsPatients diagnosed with bladder cancer (any TNM stage) from the Michigan Department of Health and Human Services (2004-2019) were retrospectively analyzed. ADI was assigned based on patients' residential census-block group and stratified into quartiles, with the fourth quartile (ADI 75-100) representing the most deprived. Multivariable logistic regression tested the impact of ADI on advanced disease stages (muscle invasive disease [≥T2], positive nodal status [cN+], metastatic disease [cM+]).
resultsAmong 29 010 patients, the majority were non-Hispanic White (92%), males (75%), and residents in metropolitan areas (81%). Patients in the third and fourth ADI quartiles had higher rates of ≥T2 (22%, 24.5%) compared with the first and second quartiles (18%, 19.5%) (P < .001), as well as increased rates of cN+ (3.4%, 3.7%) and cM+ (2.8%, 3.2%) (P < .001). Multivariable regression showed that each 10-unit rise in ADI increased odds of T2 by 4% (95% CI = 1.03 to 1.06, P < .001), cN+ by 4% (95% CI = 1.01 to 1.07, P = .038), and cM+ by 6% (95% CI = 1.02 to 1.09, P = .003).
conclusionHigher ADI correlates with advanced bladder cancer stages at diagnosis. Addressing these disparities is essential to improve outcomes in bladder cancer care.
