Investigating the Link Between Smoking and Fatty Liver via Ultrasound Elastography: A Cross-Sectional Analysis Study.
Article in Canadian journal of gastroenterology & hepatology, 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
objectiveTo investigate the link between smoking and fatty liver, particularly the influence of different smoking patterns on its prevalence, aiming to provide insights for public health policies. PATIENTS AND
methodsWe conducted a cross-sectional analysis of data from 6140 adults participating in the NHANES between 2017 and 2020. Participants were categorized into nonsmoking, secondhand smoke exposure, and active smoking groups based on serum cotinine levels. Multivariable regression models were used to assess the associations between smoking status and fatty liver, controlling for potential confounders.
resultsActive smokers showed a significantly higher prevalence of fatty liver compared to nonsmokers, especially among obese subgroups. In obese populations, both active smoking and secondhand smoke exposure remarkably increased the risk of fatty liver (OR = 2.51, p = 0.014). In contrast, a negative but statistically nonsignificant association was found between smoking and fatty liver in nonobese individuals.
conclusionTherefore, smoking, particularly among obese individuals, is a significant contributor to fatty liver. Raising public awareness of the risks associated with smoking could help enhance liver health and overall quality of life.
