Observational Study: Lung Function and Symptom Control in Youth With Asthma up to 34 Months After COVID-19.
Observational study in Pediatric pulmonology, 2025. 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
introductionPrior studies of pediatric asthma control and lung function after COVID-19 have been limited by short follow-up intervals. We aimed to evaluate symptom control and lung function in children with asthma up to 34 months post-COVID-19.
methodsWe conducted a prospective observational chart review study. We reviewed electronic health records of children with asthma in the Western Pennsylvania COVID-19 Registry, abstracting pre- and all post-infection spirometry results and Childhood Asthma Control Test (C-ACT) or Asthma Control Test (ACT) scores (to measure symptom control) through August 2023. We conducted adjusted mixed models with linear spline to compare C-ACT/ACT or FEV
resultsWe found no significant differences between baseline and post-infection symptom control (n = 267) or lung function (n = 196). Of the 28% of children who had worse lung function at initial follow-up, 34% fully recovered at final follow-up. Of the 19% with worse C-ACT/ACT score at initial follow-up, 38% fully recovered at final follow-up. Final follow-up median C-ACT/ACT scores and mean FEV
conclusionThere were no significant differences between baseline and follow-up symptom control or lung function in children with asthma up to 34 months post-COVID-19. Only a small proportion of children worsened and did not recover, and decrements were generally small. Obesity was associated with impaired symptom control recovery.
