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
introductionThis study examines how prevalence and behaviors of smoking differ by ethnicity and their associations with chronic obstructive pulmonary disease (COPD) among elderly people of four ethnicities in rural southwest China.
methodsA cross-sectional survey of 5642 adults aged ≥60 years was conducted in rural southwest China. Data on the demographics, smoking habits, and post-bronchodilator spirometry were collected.
resultsAmong the participants, the prevalence of current smoking (48.8% vs 0.8%) and COPD (12.7% vs 4.5%) was significantly higher in males compared to females (p<0.01). Filtered cigarettes were the most popular form of tobacco used, comprising 76.6% of tobacco consumed. Bai ethnic minority participants had the highest prevalence of current smoking and COPD, and the highest number of cigarettes smoked per day compared to the other three studied ethnicities (p<0.01). Ha Ni ethnic minority participants had the lowest rate of smoking cessation (8.7%) and the highest rate of smoking in public places (66.8%) (p<0.01). The results of multivariable logistic regression indicated that current smokers were more likely to suffer from COPD across all four studied ethnicities (p<0.05). Further, the association of current smoking with COPD in Bai ethnicity elderly participants was stronger compared to other ethnic groups (p<0.01).
conclusionsThe present study shows that ethnicity plays a significant role in influencing both the prevalence and behaviors related to smoking among elderly people in rural southwest China. Future efforts to prevent and reduce tobacco use in rural China should consider ethnicity, as culturally tailored tobacco control strategies could help prevent and manage the COPD epidemic.
