Prevalence, symptomatology and factors associated with asthma in adolescents aged 13-14 years from rural Sri Lanka: an analytical cross-sectional study.
Article in BMJ paediatrics open, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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 the most common chronic disease affecting children. However, the epidemiology of asthma in adolescents from rural geographies is lacking.
methodsAn analytical cross-sectional study was conducted in secondary schools located in the municipal council area of the rural district of Anuradhapura, Sri Lanka. Random sampling was used to select 32 grade 8 classes from 6 out of 9 schools. The prevalence and symptomatology of asthma were determined using the validated International Study of Asthma and Allergy in Childhood (ISAAC) questionnaire and asthma symptom control using the asthma control test (ACT) translated into Sinhalese.
resultsThe study sample consisted of 1029 participants aged 13-14 years, including 528 (51.3%) boys and 501 (48.7%) girls. The prevalence of wheeze ever, current wheeze and wheeze while playing was 32.6% (n=335), 23.7% (n=244) and 25.2% (n=259), respectively. The prevalence of parent-reported physician-diagnosed asthma was 19.0% (n=196; 95% CI 16.7 to 21.6). Severe asthma was reported by 157 (15.3%; 95% CI 13.1 to 17.6) adolescents. The independent factors associated with severe asthma were sleeping on a cloth laid on the floor instead of a bed (p<0.02, adjusted-OR 9.72; 95% CI 1.56 to 60.78), cooking using sawdust (p=0.04, adjusted-OR 8.71; 95% CI 1.10 to 68.69) eczema (p<0.01; adjusted-OR 7.39; 95% CI 3.34 to 16.39) and allergic rhinitis (p<0.01; adjusted-OR 5.50; 95% CI 3.80 to 7.98). While having a cemented floor in the house (p<0.04; adjusted-OR 0.68; 95% CI 0.47 to 0.99) was a protective factor. Poor control of asthma symptoms was detected in 29 (29.9%) adolescents which was associated with comorbid allergic rhinitis (p<0.01; unadjusted-OR 5.40; 95% CI 1.84 to 15.82).
conclusionAlmost one in four adolescents had current wheeze, and 15.3% had severe asthma. Severe asthma was independently associated with allergic rhinitis, eczema, cooking using sawdust as fuel and sleeping on a cloth on the floor instead of a bed. Poor symptom control was found in 29.9% of severe asthmatics which was associated with comorbid allergic rhinitis.
