Feasibility and Measurement Quality of Home-Based Smartphone Spirometry in Children With Suspected Asthma: A Multicentre, Prospective Study.
Article in Pediatric pulmonology, 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
backgroundDiagnosing asthma in children is challenging due to the episodic nature of symptoms and limitations of in-clinic lung function testing. Smartphone spirometry offers a potential solution by enabling repeated measurements in real-life settings. However, data on its feasibility in children with suspected but unconfirmed asthma are limited.
objectiveTo evaluate compliance, measurement quality, and agreement between manual and automated grading of smartphone spirometry in children with suspected asthma.
methodsIn this multicentre, prospective study, 102 children aged 5-16 years with suspected asthma received a smartphone spirometer and were instructed to perform daily spirometry for 7 days. Measurement quality was assessed using ATS/ERS 2019 criteria by both manual review and automated device grading. Associations with age, supervision, and social factors were analysed.
resultsOf 101 children with technically valid data, 93.1% performed at least one measurement series at home, while 31.7% completed measurements on all seven study days. Clinically usable measurement quality (grades A-C for both FEV
conclusionSmartphone spirometry is feasible for home-based lung function assessment in children with suspected asthma. Compliance and measurement quality were moderate but acceptable for clinical interpretation in most participants. Automated grading aligns well with manual review though potential discrepancies should be considered in clinical decision-making.
