Does First-Time Colon Cancer Screening Beyond Age 75 Reduce Cancer Risk Without Significant Complications? Insights From a Large US Retrospective Study.

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
introductionColorectal cancer (CRC) is a leading cause of global cancer-related morbidity and mortality. This study examines the impact of first-time screening colonoscopy on CRC incidence in obese individuals aged 75 and older using a large US retrospective cohort.
methodsObese adults aged ≥ 75 were divided into two groups: those undergoing their first screening colonoscopy after 75 (Cases) and those without prior colonoscopy (Controls), using TrinetX database data.
resultsPropensity-matched cohorts of 123,930 patients each showed reduced CRC incidence (0.08% vs. 0.52%; OR: 0.157, p < 0.001) and lower all-cause mortality (9.6% vs. 17.3%; OR: 0.510, p < 0.001) in the colonoscopy group. The number needed to treat to prevent one CRC case was 227. Perforation rates were similar (0.2%, p = NS), but gastrointestinal bleeding was higher (5.2% vs. 4.4%; OR: 1.187, p < 0.001).
conclusionScreening colonoscopy after age 75 significantly reduces CRC incidence and mortality, with manageable complication rates.
