Prevalence of and risk factors for asthma among people aged 45 and older in China: a cross-sectional study.
Article in BMC pulmonary medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers.
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
backgroundAsthma is one of the most prevalent chronic respiratory diseases worldwide. This study aimed to determine the updated prevalence of and risk factors for asthma among individuals aged 45 and older in mainland China.
methodsThe data for this study came from the fourth wave of the China Health and Retirement Longitudinal Study (CHARLS) conducted by the National School of Development of Peking University in 2018. The CHARLS is a nationally representative survey targeting populations aged 45 and over from 28 provinces/cities in mainland China. A representative sample of 19,816 participants was recruited for the study using a multistage stratified sampling method. The prevalence of asthma was determined across different characteristics. The potential risk factors were examined by multivariable logistic regressions.
resultsA total of 18,395 participants (8744 men and 9651 women) were eligible for the final data analysis. The estimated prevalence of asthma among Chinese people aged ≥ 45 years in 2018 was 2.16% (95% CI 1.96-2.38). The prevalence of asthma significantly differed according to race (P = 0.002), with an overall rate of 2.07% (95% CI 1.86-2.29) in Han paticipants and 3.32% (95% CI 2.50-4.38) in minority participants. Furthermore, the minority ethnicities (OR = 1.55 [95% CI 1.12-2.14], P = 0.008), older age (60-69 years group: OR = 1.85 [95% CI 1.17-2.92], P = 0.008; ≥ 70 years group: OR = 2.63 [95% CI 1.66-4.17], P < 0.001), an education level of middle school or below (middle-school education: OR = 1.88 [95% CI 1.15-3.05], P = 0.011; primary education: OR = 2.48 [95% CI 1.55-3.98], P < 0.001; literate: OR = 2.53 [95% Cl 1.57-4.07], P < 0.001; illiterate: OR = 2.78 [95% CI 1.72-4.49, P < 0.001]), smoking (OR = 1.37 [95% CI 1.11-1.68], P = 0.003), and residence in North (OR = 1.52 [95% CI 1.11-2.09], P = 0.01) or Northwest China (OR = 1.71 [95% CI 1.18-2.49], P = 0.005) were associated with prevalent asthma.
conclusionsAsthma is prevalent but underappreciated among middle-aged and elderly people in China. A number of risk factors were identified. These results can help to formulate correct prevention and treatment measures for asthma patients.
