Disparities in Colorectal Cancer Screening and Diagnoses in the COVID Era: A Study of the VA Health System.
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. 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
backgroundThe coronavirus disease-2019 (COVID-19) pandemic caused disruptions in cancer screening and diagnosis, including colorectal cancer. Given disparities in cancer and COVID-19 faced by historically disadvantaged minorities, we examined changes in disparities in colorectal cancer screening and diagnosis in the COVID era. PATIENTS AND
methodsIn a cohort study using the Veterans' Affairs Health Care System (VAHCS) from 2018 through 2021, we quantified colonoscopies, fecal occult blood tests (FOBT), and new diagnoses of colorectal cancer (CRC) by month from 1 March 2018 to 31 December 2021. We compared the pre-COVID (before 1 March 2020) to the COVID (1 March 2020 and after) era. We graphed temporal trends by age, sex, race, ethnicity, rural-urban, and socioeconomic status (SES). Logistic regression was used to evaluate temporal trends after adjusting for confounders.
resultsDuring the study period, there were about 900,000 colonoscopies, 1.4 million FOBTs, and > 30,000 new diagnoses of CRC. Colonoscopies and new CRC decreased dramatically during the early COVID era to < 10% and < 60% of pre-COVID rates, respectively. Although we identified a modest increase in disparities of colonoscopy use among Black and Latino patients in the early COVID era, these increased disparities did not persist in adjusted analysis. We did not identify changes in disparities in FOBT use or new CRC diagnoses.
conclusionsWe did not identify increased disparities in CRC screening or diagnoses by age, sex, race, ethnicity, geographic region, or SES in the VAHCS. These results indicate a potential strength of the VAHCS and require further study in additional cancers and healthcare systems.
