Pet Ownership Increases the Exhaled Nitric Oxide and Asthma Severity in Children With Atopic Asthma.
Article in Allergy, asthma & immunology research, 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
Exposure to pets can trigger symptoms in asthmatic children sensitized to pets. However, little is known about the association between pet ownership and asthma morbidity in children who are not sensitized to pets. We aimed to investigate the effect of pets on lung function, airway inflammation, and morbidity in children with asthma, and to determine whether the effect of exposure to pets vary based on pet sensitization status. A total of 975 asthmatic children, aged 5-15 years, were enrolled in the Korean Childhood Asthma Study. Pet ownership and asthma morbidity were evaluated by questionnaires or pediatrician evaluations. Pulmonary function, fractional exhaled nitric oxide (FeNO), and atopic status were assessed. FeNO levels were significantly higher in children with pets than in those without pets. Pet ownership significantly increased FeNO levels in atopic asthmatic children, irrespective of pet sensitization status. In children sensitized to pets, the geometric mean was 46.6 (range of 1 standard deviation, 26.9-81.5) for those with pets vs. 27.2 (13.8-53.6) for those without pets (
