Evaluating Risk Factors for Early-Onset Colorectal Cancer in a Large, Prospective Cohort.
Article in Digestive diseases and sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundDespite the worrisome rise of early-onset colorectal cancer (EOCRC), risk factors have not been definitively established. We use a large, granular database to evaluate risk factors for EOCRC, investigate differences in associations with EOCRC and later-onset CRC (LOCRC), and compare metrics of accelerated aging, a hypothesized driver of EOCRC.
methodsThis was a case-control analysis within the UK Biobank. Risk factors for each cancer were identified and compared, including aging measures (chronological age, telomere length, PhenoAge, and homeostatic dysregulation).
resultsA total of 31,164 persons were matched. We found an increased risk of EOCRC with PRS (OR 1.53; 95% CI 1.19-1.97; p < 0.001). LOCRC was associated with increasing PRS (OR 1.48; 95% CI 1.44 - 1.53; p < 0.001), increasing waist-to-hip ratio (OR 5.81; 95% CI 3.25 - 10.38; p < 0.001), family history of CRC (OR 1.27; 95% CI 1.16 - 1.40; p < 0.001), and history of smoking (OR 1.11; 95% CI 1.03 - 1.19; p = 0.01). Male sex and prior CRC screening were associated with reduced risk of LOCRC. The inclusion of PhenoAge as the measure of aging demonstrated the best model fit for both EOCRC and LOCRC. For each year that PhenoAge exceeded chronological age, the odds of EOCRC increased by 7%, while odds of LOCRC only increased by 1%.
conclusionsWithin this study, we find that genetic risk variants are a significant driver of EOCRC risk. Accelerated aging appears to be associated with increased risk of both EOCRC and LOCRC, and measures such as PhenoAge warrant continued study.
