Abstract
En 中文
• ETI induces rapid, measurable changes in exhaled volatile organic compounds. • Breath VOCs shift towards healthy levels within one week of ETI initiation. • Real-time PTR-MS enables non-invasive, point-of-care breath monitoring in CF. • Multilevel statistics identify monotonous and non-monotonous VOC trajectories. • Ten VOCs correlate with lung function and sweat chloride.tab.
