Acute effects of midwakh smoking on plasma nicotine levels and cardiopulmonary function.
Article in Annals of thoracic medicine. 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
backgroundMidwakh smoking is the second most widely used form of smoking in the United Arab Emirates predominantly among adults. Despite high prevalence, there is a lack of scientific data on plasma nicotine after a single midwakh session and its effect on cardiopulmonary function. This study assessed the acute effects of midwakh smoking on plasma nicotine levels and cardiopulmonary function after a single session.
methodsAmong 211 midwakh smokers who visited the Sleep Disorders Specialized Clinic, 9 (nine) agreed to participate in the study. Blood samples were collected before and after smoking (5 min) to determine the nicotine and cotinine levels using mass spectroscopy. Anthropometric data, smoking details, physiological parameters, heart rate variability (HRV), spirometry, and forced oscillation technique were measured pre- and post-smoking.
resultsThe mean age of the participants was 35.2 (10.2) years, and they started midwakh smoking at 20.33 (8.5) years. Plasma nicotine levels significantly increased from 14.67 (9.73) to 28.18 (12.92) ng/ml from baseline to postsmoking (
conclusionThis study involving a small sample demonstrates changes in blood nicotine and cotinine levels and differences in cardiopulmonary function among midwakh smokers; however, findings should be interpreted with caution due to limited generalizability.
