Associations Between Prescreening Dietary Patterns and Longitudinal Colonoscopy Outcomes in Veterans.

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
Background: Understanding associations between diet and long-term risk for colorectal cancer (CRC) among US veterans may provide insight for patient-clinician decisions about lifestyle recommendations as part of a CRC screening program. Methods: Asymptomatic US veterans aged 50 to 75 years who received screening colonoscopy between 1994 and 1997 were followed through 2009. The most significant colonoscopy findings (MSCFs) across the study period were classified as no neoplasia, not advanced adenomas, or advanced neoplasia (AN). The food frequency questionnaire was used to calculate raw and percent scores for the Healthy Eating Index (HEI), Mediterranean diet (MD), and Dietary Approaches to Stop Hypertension (DASH) dietary patterns. In cross-sectional analyses, multinomial logistic regression models tested for associations between dietary pattern scores and MSCF, controlling for demographics. Results: Among 3023 participants with complete data, 96.7% were male, and 83.8% were non-Hispanic White. Higher dietary patterns scores (ie, healthier diet) had similar or lower adjusted odds ratios (aORs) for AN vs no neoplasia (HEI: aOR, 1.00 [95% CI, 0.99-1.01]; MD: aOR, 0.95 [95% CI, 0.90-1.00]; DASH: aOR, 0.99 [95% CI, 0.98-1.00]). Higher grain category scores generally had lower aORs for AN for each dietary pattern (HEI: aOR, 0.96 [95% CI, 0.93-0.99]; MD: aOR, 0.29 [95% CI, 0.14-0.62]; DASH: aOR, 0.86 [95% CI, 0.78-0.95]). Conclusions: Healthy dietary patterns were associated with lower aORs for colonic neoplasia among veterans enrolled in a CRC screening program. More research is needed to determine the role of dietary assessments for tailored CRC prevention and surveillance.
