Disparities in smoking behaviors between Han and Yi: a cross-sectional survey study in Sichuan, China.
Article in BMC 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
introductionIn China, there are disparities in smoking behaviors among different ethnic groups. However, the specific disparities and their influencing factors haven’t been deeply studied.
methodsThis cross-sectional study enrolled residents aged ≥ 15 years from four geographically and economically diverse regions of Sichuan Province, China, in 2022. We employed binary logistic regression and negative binomial regression models to examine ethnic disparities in smoking status and daily cigarette consumption, respectively. The analysis presented both unadjusted estimates and estimates adjusted for a range of sociodemographic and smoking-related covariates.
resultsA total of 5,671 urban and rural residents were included; Yi participants comprised 8.22% of the sample. After multivariable adjustment, the smoking rate and daily cigarette consumption among the Yi ethnic group were significantly higher than those of the Han. Subgroup analyses revealed that among Yi individuals, middle-aged individuals were more likely to smoke than younger adults (adjusted odds ratio[AOR] = 2.84, 95% confidence interval [CI] [1.15, 7.02]). Married individuals (AOR = 3.40, 95% CI [1.16, 9.94]) and widowed/divorced individuals (AOR = 15.22, 95% CI [2.07, 117.73]) were more likely to smoke than unmarried people. Compared with individuals with an annual income of ¥10,000 or less, those with an annual income of ¥50,000 or more were also more likely to smoke (AOR = 2.84, 95% CI [1.15, 7.02]).
conclusionsAmong the Yi ethnic group, middle-aged people, married, widowed/divorced, individuals with an annual income of ≥¥50,000 should be prioritized for intervention to reduce tobacco use.
