[Prevalence of pediatric asthma in the rural areas of China: a Meta analysis].
Synthesis in Zhongguo dang dai er ke za zhi = Chinese journal of contemporary pediatrics, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
objectiveTo systematically review the prevalence of pediatric asthma in the rural areas of China, and to provide data for the prevention and treatment of pediatric asthma.
methodsPubMed, Cochrane, China National Knowledge Infrastructure, Wanfang Database, and Embase were searched for cross-sectional studies on the prevalence of pediatric asthma in the rural areas of China published up to August 31, 2019. Two researchers independently conducted preliminary screening and data extraction. Stata 14.0 and R software were used to perform a Meta analysis of prevalence rate. Subgroup analysis was also performed.
resultsA total of 24 articles were reviewed, with a sample size of 212 814 children, among whom there were 3 254 children with asthma, with an overall prevalence rate of 2.02% (95%CI: 1.67%-2.36%). Boys had a significantly higher prevalence rate than girls (3.64% vs 2.03%, P<0.001). The annual prevalence rate increased from 1.21% in 1990-1999 to 3.36% in 2011-2015. The prevalence rate of pediatric asthma was 3.15% in South China, which was higher than that in East China (2.31%), Southwest China (2.15%), North China (1.19%), and Central China (1.12%). Preschool children had the highest prevalence rate of 2.63%, followed by infants and young children (2.48%) and school-age children (1.41%).
conclusionsThe prevalence rate of pediatric asthma is relatively low but tends to increase in the rural areas of China. Boys have a higher prevalence rate of asthma than girls, and the prevalence rate is higher in South China. Preschool children have the highest prevalence rate.
