Recurrent wheezing phenotypes after severe bronchiolitis and progression to asthma.
Article in The journal of allergy and clinical immunology. Global, 2023. 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
Background: Recurrent wheezing, a common diagnosis after severe bronchiolitis, has multiple phenotypes of uncertain relation to childhood asthma. Objective: Among infants hospitalized for bronchiolitis, we investigated the relation of three 2020 recurrent wheezing phenotypes by age 4 years to asthma by age 6 years. Methods: In a 17-center cohort study of infants hospitalized with bronchiolitis, we investigated the National Heart, Lung, and Blood Institute (NHLBI) 2020-defined recurrent wheezing phenotype and 2 additional phenotypes based on this definition: multitrigger and severe. As a sensitivity analysis, we examined the NHLBI 2007 recurrent wheezing phenotype. We calculated the proportion of study subjects who developed asthma by age 6 years and used multivariable logistic regression to examine characteristics associated with the highest-risk 2020 phenotype. Results: Of 921 infants, 632 (69%) developed NHLBI 2020 recurrent wheezing, 734 (80%) developed multitrigger wheezing, and 165 (18%) developed severe wheezing by age 4 years; in addition, 296 (32%) developed NHLBI 2007-defined recurrent wheezing by age 3 years. Of 862 children with sufficient data (94%), 239 (28%) developed asthma by age 6 years. The proportions of children who progressed to asthma were as follows: 33% of those with NHLBI 2020-defined wheezing, 33% of those with multitrigger wheezing, 54% of those with severe wheezing, and 52% of those with NHLBI 2007-defined recurrent wheezing. The children with the severe phenotype who developed asthma had the associated characteristics preterm birth, child eczema, maternal asthma, and non-respiratory syncytial virus infection. Conclusion: Most infants with severe bronchiolitis developed the NHLBI 2020-defined recurrent wheezing phenotype by age 4 years. Depending on the phenotype, 33% to 54% will develop asthma by age 6 years. Future research will examine whether earlier treatment of high-risk phenotypes will improve wheezing symptoms and potentially prevent childhood asthma. (J Allergy Clin Immunol Global 2023;2:84-7.).
