Prevalence and risk factors for childhood asthma: a systematic review and meta-analysis.
Synthesis in BMC pediatrics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 42 papers, 4 of them syntheses that pooled it.
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
backgroundThis study aimed to systematically review and perform a meta-analysis on epidemiological studies in order to estimate the global and regional prevalence and to identify risk factors associated with childhood asthma.
methodsA comprehensive search of the PubMed, Embase, and Cochrane Library electronic databases was conducted for relevant literature published from their inception to March 31, 2023. The primary endpoint was the prevalence of childhood asthma. Secondary endpoint focused on the identification of risk factors associated with childhood asthma.
resultsA total of 1,547,404 children participated in the 164 studies selected for the meta-analysis. The overall prevalence of childhood asthma was 10.2% (95% CI: 9.5-11.0%), while the prevalence of childhood asthma in Asia, Europe, Latin America, North America, Oceania, Africa, or Eurasia were 10% (95%CI: 7-13%), 9% (95%CI: 7-12%), 14% (95%CI: 9-20%), 13% (95%CI: 12-14%), 23% (95%CI: 19-28%), 11% (95%CI: 7-19%), and 8% (95%CI: 2-27%), respectively. Moreover, the identified risk factors for childhood asthma included older age, male sex, obesity, parental smoking, high education of the mother, premature birth, cesarean section, no breastfeeding, family history of asthma, rhinitis, eczema, pets, high density of road traffic, meat, margarine, fast food, paracetamol use, and antibiotic use.
conclusionChildhood asthma is common, and the prevalence of asthma is highest in Oceania, with a lower prevalence in Eurasia. Moreover, the risk factors for childhood asthma were comprehensively identified, and health education should be provided to prevent modifiable factors.
