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
backgroundExcessive drinking is a known risk factor for psychological distress; however, the role of alcohol tolerance in this relationship remains unclear. This study examined the association between excessive drinking and psychological distress among agricultural workers in Japan by focusing on the potential moderating effect of alcohol tolerance.
methodsA cross-sectional questionnaire survey was conducted among agricultural workers in City A, Akita Prefecture, Japan, between November 2024 and January 2025. Excessive drinking was defined as an alcohol use disorders identification test score ≥ 15, and psychological distress was assessed using the Kessler 6 scale (cut-off ≥ 13). Alcohol tolerance was determined based on self-reported facial flushing. Multivariate logistic regression analysis was performed to examine associations after adjusting for confounders. Stratified analyses were conducted to assess differences based on alcohol tolerance.
resultsAmong the 169 participants, 15 (8.8%) reported psychological distress. Excessive drinking was significantly associated with psychological distress (odds ratio [OR] 6.41, 95% confidence interval [CI] 1.62-25.28, p < 0.001). Stratified analysis showed a significant association only among individuals with alcohol tolerance (OR 28.66, 95% CI 3.26-251.89, p < 0.001), whereas no significant association was observed among those without alcohol tolerance (OR 0.88, 95% CI 0.09-8.54, p = 0.91).
conclusionsAlcohol tolerance moderated the relationship between excessive drinking and psychological distress. These findings suggest that alcohol tolerance may be an important factor to consider when examining this association.
