Diagnostic performance of colonoscopy after positive FIT in National Cancer Screening Program.
Article in Medicine, 2026. 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
The National Cancer Screening Program of Korea provides an annual fecal immunochemical test (FIT) for adults aged ≥50 years. We evaluated the diagnostic performance of colonoscopy and the prevalence ratio (PR) of advanced neoplasia (AN) in participants with positive FIT results under the National Cancer Screening Program between 2007 and 2024. The PR of AN was compared between binary groups created based on age, sex, waiting time to colonoscopy, FIT cutoff value, and anemia. Among the 2445 participants with positive FIT results, 1237 (50.6%) underwent colonoscopy. The positive predictive values for non-AN, AN, and sessile serrated lesions were 31.2%, 15.4%, and 14.6%, respectively. The PR of AN was 1.8 times higher in males than in females (P < .001) and 1.9 times higher in the standard FIT cutoff group than in the low FIT cutoff group (P < .001). In the multivariable analysis, male sex (PR = 1.84, 95% confidence interval: 1.36-2.50) and FIT positivity based on the standard cutoff (PR = 1.86, 95% confidence interval: 1.33-2.61) were significantly associated with AN (both P < .001). ANs were more frequently detected in male participants and when the standard FIT cutoff value was used in FIT-based colorectal cancer screening. Given the low colonoscopy completion rate of only 50.6%, colonoscopy completion should be recommended, particularly for male participants and those with positive FIT results based on the standard cutoff value.
