Socioeconomic and Geographic Disparities in Anorectal and Urinary Procedures Following Radiotherapy for Prostate Cancer.
Article in Cancer medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
background and purposeEvidence on how treatment outcomes vary by patient characteristics helps to inform clinical practice. In this study, we measured socioeconomic and geographic disparity in post-radiotherapy procedures, as an indication of short-term radiotherapy adverse effects, among men with prostate cancer. MATERIALS AND
methodsWe studied 8344 South Australian diagnosed men with prostate cancer (2002-2020) who received external beam radiotherapy. The outcomes were anorectal and urinary procedures, identified using hospital admission procedure codes and Medicare Benefits Schedule item codes. Crude rates per 1000 person-time were estimated at two years post-radiotherapy. Socioeconomic and geographic disparities were identified through multivariable adjusted zero-inflated Poisson regression.
resultsFifteen percent of men underwent at least one post-radiotherapy procedure within two years. The rates of anorectal, urinary and overall (both anorectal and urinary) procedures were 18, 66 and 81 per 1000 person-years, respectively. Men in the highest socioeconomic quintile had lower rates of overall (incidence rate ratio [IRR] 0.70, 95% CI: 0.61-0.81), anorectal (IRR 0.32, 95% CI: 0.20-0.52) and urinary (IRR 0.69, 95% CI: 0.56-0.86) procedures than men in the lowest socioeconomic quintile. Men from non-metropolitan areas had higher rates of anorectal procedures (IRR 1.36, 95% CI: 1.05-1.77) than men from metropolitan areas, which was further compounded by low socioeconomic advantage. Receiving radiotherapy in more recent years was associated with lower rates of post-radiotherapy procedures.
conclusionAnorectal and urinary procedures following radiotherapy significantly vary across different population subgroups. Observed differences in procedure rates may suggest socioeconomic and geographic disparities in radiotherapy adverse effects for prostate cancer. This underscores the importance of follow-up care for at-risk population subgroups.
