https://doi.org/10.2147/copd.s603467This proof-of-concept study investigated whether salivary metabolomics could identify biomarkers for COPD and disease severity. Researchers analysed saliva from 47 COPD patients and 48 controls, finding metabolite patterns associated with COPD and airflow obstruction. A Vitalograph Alpha spirometer was used at enrolment to measure lung function (FEV₁), classify COPD severity, and correlate salivary biomarkers with airflow obstruction
