Cat exposure and asthma outcomes in a cohort of children with asthma and allergy.
Article in Frontiers in allergy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Introduction: The impact of current pet exposure on children with allergic asthma is not yet fully understood. This study aimed to investigate the association between cat exposure and asthma outcomes in children with established asthma and allergy. Methods: A population-based cohort study using Swedish national health, sociodemographic, and quality registers was conducted. We included 30 277 children aged 4-17 years (born 2006-2020), with validated diagnoses of asthma and allergy, who had asthma care during the two years preceding exposure assessment. Cat exposure was defined as parental cat ownership recorded in the National Cat Register in 2023. Asthma outcomes, assessed during 2023-2024, included: asthma exacerbation and moderate-to-severe asthma. In a subset with available data ( Results: Of the study population (median age: 9.5 years, 39% females), 9.4% ( Conclusion: In this cohort of children with asthma and allergy, no association between cat exposure and asthma exacerbations, severity, lung function, or asthma control was observed. These findings suggest that cat exposure may not adversely affect asthma outcomes in this population.
