Effects of alcohol consumption from early adolescence on lung function and development of COPD - a retrospective cohort study.
Article in European clinical respiratory journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Studies indicate a U-shaped relationship between alcohol consumption (AC) and chronic obstructive pulmonary disease (COPD) with low-moderate AC being protective. We investigated the influence of AC debut (ACD) at different ages on forced expiratory volume in the first second (FEV1), forced vital capacity (FVC) and COPD development. Methods: In a multi-center cohort study, data on AC were collected through a questionnaire and spirometry performed at baseline and follow-up. COPD was defined as FEV1/FVC-ratio <0.7 on post-bronchodilator spirometry. Modelling determined odds ratio (OR) of COPD and mean differences in FEV1 and FVC in stratified age groups of ACD. Never drinkers were used as reference. Adjustments were made for age, sex, smoking parameters, asthma, and education. Results: In total, 4,717 participated in the initial work-up and 2,751 completed follow-up. A higher FEV1 and FVC was found in all groups compared to never drinkers. Highest statistically significant difference in FEV1 and FVC was found in age group 14-16 (0.17 and 0,23 L, respectively). With rising age of ACD a smaller difference in FEV1 and FVC was observed with the smallest difference in age group >25 (0.11 L) and age group 17-18 (0.13 L), respectively. A lower, but not statistically significant OR for COPD in ACD age 14-16 (OR = 0.83) and higher OR in the remaining groups with 21-25 being highest (OR = 1.36) was indicated. Conclusion: This study found higher FEV1 and FVC in all groups drinking alcohol compared to never drinkers with the highest among participants with ACD at age 14-16. The findings on risk of COPD development were not statistically significant.
