Screening asymptomatic school children for early asthma by determining airway narrowing through peak expiratory flow rate measurement.
Article in Journal of education and health promotion, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundPeak expiratory flow rate (PEFR) is widely used as a predictor of treatment of asthma patients. Peak expiratory flow and forced expiratory volume in first second (FEV MATERIALS AND
methodsWe selected 200 asymptomatic children at the age of 10-15 years without a history of smoking, tuberculosis, or other respiratory illness. A family history about asthmatic symptoms was sought. PEFR values of all children were recorded, and 40 children showed PEFR values less than 80% of their predicted values. To confirm whether the low observed values were because of airway obstruction, their spirometry was performed.
resultsNine out of 47 (19.14%) children from asthmatic families and 31 out of 153 (20.26%) from nonasthmatic families showed PEFR values <80% of the predicted value (
conclusionsAsymptomatic children with low PEFR values may not show abnormal lung functions on spirometry. However, these children, particularly those having the risk of family history of asthma, may be followed for the development of airway obstruction.
