Quizplus · Accepted Answer

Forced expiratory volume after 1 second (FEV1) and forced vital capacity (FVC) are the two most important pulmonary function test markers that correlate with mortality in patients with cystic fibrosis. Both of these markers are commonly used to monitor disease progression and response to treatment, and individuals with lower FEV1 and FVC values have been shown to have a higher risk of mortality.
