Smartphone spirometry offers a potential solution by enabling repeated measurements in real\u2010life settings. However, data on its feasibility in children with suspected but unconfirmed asthma are limited.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>To evaluate compliance, measurement quality, and agreement between manual and automated grading of smartphone spirometry in children with suspected asthma.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>In this multicentre, prospective study, 102 children aged 5\u201316 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.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Of 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\u2013C for both FEV\n                      <jats:sub>1<\/jats:sub>\n                      and FVC) was achieved at least once by 61.7% (manual grading) and 74.5% (automated grading). Automated grading showed strong correlation and high agreement with manual grading (ICC\u2009=\u20090.90), but slightly overestimated quality. Measurement quality was not significantly associated with age, supervision, or social factors.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Smartphone spirometry is feasible for home\u2010based lung function assessment in children with suspected asthma.
