The association between body mass index and frequency of emergency department visits and hospitalization for asthma exacerbation in a pediatric population.
Article in Annals of Saudi medicine. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundThe prevalence of both asthma and obesity are increasing. Although some studies suggest an association between body mass index (BMI) and frequency of emergency department (ED) visits and hospitalization for asthma exacerbation, any association remains unproven.
objectiveEstimate the frequency of asthma exacerbation in obese children, and identify any relationship between BMI and frequency of ED visits and hospitalization for asthma exacerbation.
designRetrospective review of medical records. SETTINGS: Tertiary children's hospital, Riyadh. SUBJECTS AND
methodsAll children aged 2-15 years who attended the ED for asthma exacerbation between January 2015 and January 2016 were included. Children with comorbidities or undocumented asthma were excluded. The Centers for Disease Control and Prevention BMI-for-age growth charts for boys and girls aged 2 to 20 years were used to classify underweight, normal, overweight, and obese.
main outcome measuresThe frequency of ED visits and the rate, frequency, and duration of hospitalization.
resultsOf the 1000 cases reviewed, 64.6% were boys and the mean age (standard deviation) of all sub.jects was 5.6 (3.3) years. The proportions of overweight and obese children was 11.8% and 12.1%, respectively. There was no association between increased BMI and frequency of ED visits for asthma exacerbation (P=.84), duration of hospitalization (P=.41) or frequency of hospitalization (P=.89).
conclusionThere was no evidence of an association between BMI and frequency of ED visits and hospitalization for asthma exacerbation among children. LIMITATIONS: This study included patients as young as 2 years, while asthma is only well-defined in children > 5 years. Asthma triggers that can cause exacerbation despite body weight were not included. We included only frequency of ED visits and hospitalization, which may be inadequate to measure asthma severity.
