Spirometric Lung Function Among Smokers and Non-Smokers: A Cross-Sectional Study in University Students.
Article in International journal of environmental research and public health, 2026. 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
backgroundWith the increasing use of cigarettes and electronic nicotine delivery systems (ENDS) in young adults, growing concern exists regarding lung health among university students. While the adverse respiratory effects of smoking are well established in older populations, early functional changes among young adults remain less well studied. Identifying such changes in this vulnerable population is crucial due to the risk of detrimental long-term health effects and the role of implementing early preventive measures. This study aims to compare the effects of nicotine use, sex, and body mass index (BMI) on the spirometric lung function parameters, including FEV
methodsThis cross-sectional study was conducted at Ajman University, United Arab Emirates. A convenience sample of 652 smokers and non-smokers students was initially recruited voluntarily, of whom 630 participants met the spirometry acceptability criteria and were included in the final analysis. Lung function was assessed using spirometry performed according to the guidelines of the American Thoracic Society and European Respiratory Society. Forced expiratory volume in one second (FEV
resultsA total of 630 students were included (60.5% males; the majority aged 20-22 years). The prevalence of smoking was 28.9% and was significantly higher among males than females (38.6% vs. 14.1%; OR = 3.86,
conclusionsSmoking, sex, and BMI significantly influenced lung function in this cohort. Smokers demonstrated reduced FEV
