Disparities in Colorectal Cancer Screening Before and After the Onset of the COVID Pandemic.
Article in Journal of general internal medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundColorectal cancer (CRC) screening is underutilized among those with lower socioeconomic status and in racial and ethnic minoritized populations who have been disproportionately impacted by COVID.
objectiveTo compare disparities in CRC screening before and after the onset of the COVID pandemic among privately insured individuals.
designRetrospective cohort study using deidentified claims data from the USA between January 1, 2017, and December 31, 2022.
participantsBlue Cross Blue Shield beneficiaries aged 50-75 years with average risk of CRC. MAIN MEASURE(S): Mean screening use was compared by demographic and area-level socioeconomic factors between the periods preceding (January 1, 2017 to February 28, 2020) and following (July 1, 2020 to December 31, 2022) the onset of the COVID pandemic. Difference-in-differences analysis was used to evaluate changes in screening differences.
resultsOur study included 21,724,223 beneficiaries. Compared to males, females had higher screening in both periods (p < 0.05), and this sex difference in screening increased 1.63% (95% confidence interval [CI]: 1.32%, 1.94%) following the onset of the pandemic. Compared to residents in areas with high socioeconomic status (SES), low SES area residents had lower screening (p < 0.001) during both periods. Furthermore, this difference grew 4.32% (95% CI, 3.76%, 4.88%) during the post-onset period. Metropolitan area residents had higher screening than non-metropolitan area residents during both periods (p < 0.001); however, this difference decreased 0.77% (95% CI, 0.34%, 1.20%) during the post-onset period. Among beneficiaries with high risk of CRC, the difference in screening based on social deprivation index and metropolitan area status increased 6.99% (95% CI, 5.77%, 8.20%) and 1.82% (95% CI, 0.88%, 2.74%), respectively.
conclusionsAmong privately insured individuals, CRC screening after the COVID pandemic recovered unevenly based on sex, area-level socioeconomic measures, and metropolitan area status, with pre-pandemic disparities persisting and even worsening for some of the factors.
