Clean Air for Asthma and Allergy Programme (CAAP), a randomized controlled trial to evaluate the effectiveness of multicomponent interventions to reduce indoor triggers in childhood asthma.
Article in Asia Pacific allergy, 2025. 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
Background: Multicomponent interventions have been reported as effective strategies for improving allergen reduction and asthma control. However, few studies have evaluated the integration of an indoor air quality (IAQ) system and e-health as part of multicomponent interventions. Objective: To evaluate the effects of multicomponent interventions on house dust mite allergens, indoor particulate matter, and knowledge and trigger reduction behaviors (TRBs) of caregivers. Methods: Twelve pediatric asthmatic patients with dust mite sensitization were randomly assigned to either a multicomponent intervention group or a control group. In the multicomponent intervention group, IAQ systems were installed in participants' bedrooms, bedding covers were provided, and asthma education was delivered through the LINE application, while the control group received conventional treatment. House dust mite allergen levels were analyzed using the enzyme-linked immunosorbent assay technique, and particulate matter <2.5 micrometer diameter (PM2.5) concentrations were measured at baseline, 4 weeks, and 8 weeks postenrollment. Questionnaires were used to evaluate TRBs and asthma knowledge among caregivers before and after the intervention. Results: There were decreased Dermatophagoides pteronyssinus allergen group 1 and Dermatophagoides farinae allergen group 1 levels in the multicomponent intervention group compared to the control group; however, the reduction was not statistically significant. Indoor PM2.5 concentrations were significantly lower in the multicomponent intervention group compared to the control group after 4 and 8 weeks ( Conclusion: Implementation of an IAQ system and asthma education through the LINE application, as part of multicomponent interventions, resulted in a significant reduction in indoor PM2.5 concentrations and improved TRBs among caregivers.
