Air Quality Index and Childhood Asthma: A Pilot Randomized Clinical Trial Intervention.
Trial report in American journal of preventive medicine, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04454125 (Air Quality Index), which is not on this map. Cited by 7 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.

Abstract
introductionTo reduce air pollution exposure, the U.S. asthma guidelines recommend that children check the Air Quality Index before outdoor activity. Whether adding the Air Quality Index and recommendations to asthma action plans reduces exacerbations and improves control and quality of life in children with asthma is unknown.
methodsA pilot, unblinded, randomized clinical trial of 40 children with persistent asthma, stratified by age and randomized 1:1, recruited from the University of Pittsburgh Medical Center Children's Hospital of Pittsburgh (Pittsburgh, PA) was conducted. All participants received asthma action plans and Air Quality Index education. The intervention group received printed Air Quality Index information and showed the ability to use AirNow. Asthma exacerbations were assessed through a questionnaire, asthma control was assessed with the Asthma Control Test and Childhood Asthma Control Test, and quality of life was assessed with the Pediatric Asthma Quality of Life Questionnaire. After randomization (July-October 2020), participants were followed monthly for 6 months (exit January-March 2021). Outcome differences between groups were evaluated at the exit visit and over time (analysis was in 2021).
resultsAt randomization, there were no significant differences in age, sex, race, or asthma severity. At exit, more intervention participants checked the Air Quality Index (63% vs 15%) with no differences in the proportion of asthma exacerbations or mean Childhood Asthma Control Test or Pediatric Asthma Quality of Life Questionnaire scores. The mean change in Asthma Control Test score was higher in the intervention group (change in Asthma Control Test=2.00 vs 0.15 for the control), which was modified by time (β=1.85, CI=0.09, 3.61). Physical activity was decreased overall and showed modification by treatment and time.
conclusionsAddition of the Air Quality Index to asthma action plans led to improved asthma control by Asthma Control Test scores but may decrease outdoor activity.
