Association of race and area of deprivation index with prostate cancer incidence and lethality: results from a contemporary North American cohort.
Article in JNCI cancer spectrum, 2024. 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
backgroundSocioeconomic and demographic factors contribute to disparity in prostate cancer (PCa) outcomes. We examined the impact of Area of Deprivation Index (ADI) and race on PCa incidence and lethality in a North American cohort.
methodsOur cohort included men who received at least 1 prostate-Specifig Antigen (pSA) test within our Health System (1995-2022). An ADI score was assigned to each patient based on their residential census block, ranked as a percentile of deprivation relative to the national level. Individuals were further categorized into quartiles, where the fourth one (ADI 75-100) represented those living in the most deprived areas. We investigated PCa incidence and lethality, using cumulative incidence estimates and competing-risk regression. An ADI × Race interaction term examined whether the relationship between ADI and outcomes varied based on race.
resultsWe included 134 366 patients, 25% of whom were non-Hispanic Black (NHB). Median (IQR) follow-up was 8.8 (5-17) years. At multivariate analysis, individuals from the third quartile (ADI 50-74, 95% CI = 0.83 to 0.95) and the fourth quartile (ADI ≥75, 95% CI = 0.75 to 0.86) showed significant reduced hazard ratios for PCa incidence, when compared with the first quartile (ADI <25, all P < .001). In contrast to the overall cohort, PCa incidence increased with ADI in NHB men, who were persistently at higher hazard for both PCa incidence and lethality than non-Hispanic White (NHW), across all ADI strata (all P < .001).
conclusionsLiving in more deprived areas was associated with lower PCa incidence and higher lethal disease rate. Conversely, PCa incidence increased with ADI for NHB, who consistently showed worse outcomes than NHW individuals, regardless of ADI.
