Pre-CPET spirometry in the three groups of patients.

Data	ICU Group n = 31	MLC Group n = 23	OB Group n = 15
FVC, % predicted	90 [72–104.5]	100 [95–110.8]	98 [90–106.5]
FEV1, % predicted	92 [80–105.5]	97.5 [89.5–104.3]	102 [89–106]
DLCO, % predicted	98 [84.5–110]	95 [82.2–101.8]	89 [84–104.5]

Data are expressed as the median with lower and upper quartiles [Q1–Q3] or count (%). DLCO: diffusion capacity of carbon monoxide; FEV1: forced expiratory volume in one second; FVC: forced vital capacity.
