The Geography of Cancer: Regional Disparities in the Incidence of Prostate Cancer in Puerto Rico, 2016-2022.
Article in Journal of racial and ethnic health disparities, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Prostate cancer remains the most prevalent malignancy and a leading cause of cancer-related mortality among men in Puerto Rico. This study evaluates regional disparities in prostate cancer incidence across 76 contiguous municipalities on the main island and characterizes areas exhibiting statistically significant spatial clustering. Using spatial analytical techniques-including Moran's I and Getis-Ord Gi*-within Geographic Information Systems (GIS), we analyze data from the Puerto Rico Central Cancer Registry (RCCPR) spanning 2016 to 2022. The findings reveal a non-random spatial distribution of prostate cancer incidence, with consistent clustering patterns observed throughout most of the study period, except in 2019. Notably, cold-spot regions were persistently identified in the northwest and western municipalities, while elevated incidence rates were concentrated in clusters located in the southern and eastern regions. These results underscore the presence of enduring geographic disparities in the prostate cancer burden across Puerto Rico.
