Peak Flow Meter and Spacer Use in Adolescents with Asthma: More than Just Ownership.
Article in Children (Basel, Switzerland), 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
backgroundEffective self-management is essential for optimizing asthma control. Although peak flow meters (PFMs) and spacers are recommended to support self-management, the associations between device use patterns and asthma outcomes remain unclear. This study aims to examine the ownership and use of devices among adolescents with asthma and their associations with asthma exacerbations in the past 12 months and asthma control.
methodsCross-sectional data from 373 inner-city adolescents with asthma were analyzed. Participants reported PFM or spacer ownership and their frequency of use. Exacerbation history was determined based on oral corticosteroid use, hospitalizations, and emergency department visits in the past 12 months. Asthma control was assessed using the Asthma Control Questionnaire. Chi-square tests and independent
resultsOwnership rates were 36% for PFMs and 61.6% for spacers. Ownership of both devices was negatively associated with asthma exacerbations in the past year (all
conclusionsAdolescents' ownership of peak flow meters and spacers remains suboptimal, and the routine adoption of these devices is limited. Adolescents with exacerbations in the past year were more likely to own devices but use them infrequently. Regular use was associated with poorer asthma control, suggesting reactive rather than preventive use. Findings highlight the need for improved education on preventive device use, enhanced training in proper use, and proactive integration of devices into adolescent asthma self-management.
