1 · What the graph read from it

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.

2 · The registry

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

backgroundColorectal cancer (CRC) remains a leading cause of cancer mortality in the United States. While screening significantly reduces CRC incidence and mortality, disparities persist, particularly between rural and urban populations. This study assessed the extent and determinants of rural-urban disparities in CRC screening using nationally representative data from the Behavioral Risk Factor Surveillance System (BRFSS) between 2019 and 2023.

methodsThe study analyzed responses from 535,568 adults using complex survey-weighted logistic regression and Blinder-Oaxaca decomposition analysis. CRC screening status was defined as a binary outcome. Independent variables included geographic classification (rural and urban), age, sex, race/ethnicity, education, income, insurance status, and access to a personal healthcare provider.

resultsOverall, 73.0% of eligible adults reported undergoing CRC screening, with a higher prevalence among urban residents (77.7%) than rural residents (74.4%). Decomposition analysis revealed that 27.5% of the rural-urban disparity was attributable to differences in measurable characteristics such as education, income, age distribution, insurance, and provider access. Educational attainment and income contributed most to the explained gap. However, 72.5% of the disparity remained unexplained, indicating potential influences from structural, cultural, and healthcare system-level factors.

conclusionSubstantial rural-urban disparities in CRC screening persist, largely driven by unmeasured contextual factors. Addressing this gap requires multifaceted, equity-focused interventions. Future research should adopt the socio-ecological model to comprehensively examine multilevel determinants influencing screening behaviors, especially within underserved rural communities.
