Discrimination of adult asthma severity via exhaled volatile organic compounds using high-pressure photoionization time-of-flight mass spectrometry: a pilot study.
Asthma is a heterogeneous airway disease that necessitates the identification of objective biomarkers to characterize inflammatory and metabolic phenotypes for precision medicine. In this study, exhaled breath from 40 adults, including 10 with moderate-persistent asthma (Mop-AS), 10 with mild-persistent asthma (Mip-AS)...
