Genetic Polymorphism in Alcohol Metabolism and Drinking Behavior Are Associated with Gastric Cancer Risk in Men.

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
Objective In recent years, there has been a growing focus on health risks associated with alcohol consumption. The present study investigated whether or not the genetic variant of aldehyde dehydrogenase 2 (ALDH2) influences the risk of gastric cancer among individuals identified as hazardous drinkers using the Alcohol Use Disorders Identification Test (AUDIT), which provides a comprehensive assessment of hazardous drinking behavior. Patients We enrolled men with hazardous drinking behavior (AUDIT score ≥8) who had undergone gastric cancer screening (either endoscopy or a barium X-ray examination of the upper gastrointestinal tract) between April 2013 and March 2020 within 1 year from entry and who had subsequently undergone at least one more gastric cancer screening up to March 2021. Functional single-nucleotide polymorphisms of ALDH2 (rs671) were measured using a direct TaqMan polymerase chain reaction method with unprocessed saliva. Results A total of 246 men were enrolled, comprising 193 individuals with active ALDH2 (ALDH2*1/*1) and 53 with less-active ALDH2 (ALDH2*1/*2). The cumulative incidence of gastric cancer in the less-active group was higher than in the active ALDH2 group (p=0.01, hazard ratio: 4.6, 95% confidence interval: 1.2-16.7). Alcohol consumption was lower in the less-active ALDH2 group than in the active ALDH2 group, although no marked difference was observed in the AUDIT score. Conclusion In individuals with hazardous drinking behavior, a heightened risk of gastric cancer was observed among those with less-active ALDH2 variants, even when their alcohol consumption was comparatively lower than in those with active ALDH2 variants.
