A delay in the diagnosis of colorectal cancer screened by fecal immunochemical tests during the COVID-19 pandemic: a longitudinal cohort study.
Article in International journal of colorectal disease, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers, 1 of them a synthesis that pooled 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.
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
purposeThere is concern that the COVID-19 pandemic may cause people to refrain from undergoing examination resulting in delayed detection of colorectal cancer (CRC). The purpose of this study was to investigate whether there was a delay in CRC detection due to withholding of screening.
methodsThe colonoscopy screening rate and the CRC detection rate were calculated for patients who underwent fecal immunochemical tests (FITs) from 2018 to 2021 in the longitudinal cohort. The stages of CRC cases detected as a result of positive FIT in each year were compared.
resultsA total of 39,521 patients were initially screened by FIT over a 4-year period. The FIT-positive rate was 4.7% (441 /9,349) in 2018, 4.6% (420 /9,156) in 2019, 4.9% (453 /9,255) in 2020, and 4.3% (504 /11,760) in 2021. The colonoscopy screening rate for positive FIT results was lower in 2020 than in 2019 (25.8% vs. 38.1%, P < 0.001), and higher in 2021 than in 2020 (56.7% vs. 25.8%, P < 0.001). The CRC detection rate among colonoscopy recipients was higher in 2021 than in 2020 (13% vs. 4%, P = 0.014). Stage 1 or higher CRC accounted for 25.0% (1/4) in 2020, and 78% (18/23) in 2021. Among the CRC cases detected each year, 1 (14%), 1 (25%), and 10 (43%) did not undergo colonoscopy despite positive FIT results in the previous year.
conclusionsThe COVID-19 pandemic has reduced the detection of CRC by screening colonoscopy following FIT and might have led to a delay in the detection of CRC.
