Sociodemographic Disparities in Rectal Cancer Outcomes within Academic Cancer Centers.
Article in Annals of surgical oncology, 2025. 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
backgroundSociodemographic disparities in cancer care outcomes are often related to delayed or limited care access. However, it is unknown whether outcome differences persist after establishing high-level care. This study evaluated the relationship between rectal cancer outcomes and sociodemographic status at academic cancer centers. PATIENTS AND
methodsA retrospective cohort study of patients with rectal cancer treated at academic cancer centers was conducted utilizing the National Cancer Database. Primary outcome was overall survival, while secondary outcomes included 30- and 90-day mortality, time from diagnosis to treatments, hospital readmission rates, and hospital length of stay.
resultsOf the 127,023 patients, median age was 62.7 years (SD 11.92), 59.3% were male, 80.3% were white, and 39.4% presented with stage III disease. After adjustment, Black patients had the worst overall survival (HR 1.10, 95% CI 1.01-1.19, p = 0.016). Private insurance status conferred overall survival benefit (HR 0.66, 95% CI 0.58-0.75, p < 0.001) as well as the best protection against 30- and 90- day postoperative mortality (30-day OR 0.31, 95% CI 0.10-0.97, p = 0.044; 90-day OR 0.37, 95% CI 0.16-0.83, p = 0.015). Black patients experienced longer time to first treatment than their white counterparts, with a delay of 3.23 days (95% CI 1.87-4.58, p < 0.001).
conclusionsThis study demonstrated the existence of sociodemographic disparities even within the walls of academic institutions, where care should be evidence-based, standardized, comprehensive, and equitable. When analyzing causal pathways, delays in time to treatment initiation may be contributing to these outcomes, but may be modifiable.
