Peak expiratory flow rate and it's determinants in adolescents from South India.

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
Background and objectives: Asthma is one among the major health problems found globally with varied prevalence depending upon the geographical location. Several genetic and environmental factors are associated with asthma in children. Our study aims at factors affecting Peak Expiratory Flow Rate (PEFR) in adolescents from Chennai, south India. Material and Methods: This observational study was carried out in Chennai schools between July 2019 to Jan 2020 with the sample size of 596 (male 56.4%). Adolescents in the age group of 11 to 14 years were included with Institutional Ethics Committee approval, school permission and consent from the participants. Information about age, gender, history, family history and environmental history was obtained through questionnaire followed by anthropometric measurements. PEFR was measured using Mini Wright peak flow meter. Multiple linear regression analysis was conducted by using SPSS (Statistical Package for the Social Sciences) version 16 with derivation of regression equation for the significant parameters. Results: There was a significant correlation of PEFR with age, gender, height, history of nebulization, family history of asthma and environmental smoke ( Conclusions: Thus, identifying the factors affecting PEFR can provide a basis for targeted prevention efforts in children and adolescents. Prediction formula derived from statistical analysis can be used in diagnosing and following adolescents with asthma from south India.
