Peak Expiratory Flow and Its Trajectories Associated With Frailty in Older Adults: A Prospective Cohort Study.
<p><b>BACKGROUND</b></p><p>Current evidence indicates an association between peak expiratory flow (PEF) and frailty in older adults, yet critical gaps persist regarding: the longitudinal dynamics of PEF trajectories, their temporal relationships with frailty progression and underlying biological mechanisms. This study aimed to...
