Prognostic value of short-term decline of forced expiratory volume in 1 s over height cubed (FEV1/Ht(3)) in a cohort of adults aged 80 and over KU Leuven
Forced expiratory volume in 1 s over height cubed (FEV1/Ht(3)) is an FEV1 expression that uses no reference values and is independently associated with adverse outcomes in older adults. No studies have reported on the prognostic value of its decline over time in adults aged 80 and over.
