SPPB= Short Physical Performance Battery. COPD=Chronic Obstructive Pulmonary Disease, BMI=Body Mass Index, FEV1=Forced Expiratory Volume in the first second, 6 MWD=Six Minute Walk Distance, LAS=Lung Allocation Score, ECMO=Extracorporeal Membrane Oxygenation. Health-related quality of life instruments: generic-physical instrument: SF12-PCS (Short Form 12–Physical Component Score), range 0 to 100; generic-mental instrument: SF12-MCS (Short Form 12–Mental Component Score), range 0 to 100; respiratory-specific instrument: AQ20-R (Airways Questionnaire 20–Revised), range 0 to 20, reverse-coded for analysis; health-utility instrument: EQ5D (EuroQoL 5D), range -1.11 to 1. Data are presented as number of patients (percentage) or mean ± standard deviation.
