Forced expiratory volume in 1 second (FEV1) is proposed as a marker of healthy ageing and FEV1 expressions that are independent of reference values have been reported to be better at predicting mortality in older adults. We assess and compare the predictive value of different FEV1 expressions for mortality, hospitalization, and physical and mental decline in adults aged 80 and older.
