General characteristics of the COPD and control group

Control (n=8) COPD (n=8) P values
Age y 63.1 ± 2.8 68.1 ± 2.2 0.186
Height m 1.74 ± 0.02 1.74 ± 0.03 0.812
Weight kg 77.5 ± 3.4 81.8 ± 3.3 0.376
BMI kg/m2 25.4 ± 0.8 27.2 ± 0.7 0.141
FFMI kg/m2 19.1 ± 0.5 17.1 ± 0.3 0.011
FEV1 % pred 110 ± 4 50 ± 4 0.000
Dlco % pred 104 ± 6 78 ± 6 0.010
FVC % pred 116 ± 4 93 ± 8 0.026
ITGV % pred 111 ± 7 146 ± 11 0.018
TLC % pred 106 ± 5 115 ± 6 0.281
RV % pred 98 ± 5 145 ± 19 0.047

Values are means ± SEM, n = 8/group. COPD: Chronic Obstructive Pulmonary Disease, BMI: body mass index, FFMI: Fat-free mass index, FEV1: forced expiratory volume in one second, Dlco: diffusing capacity for carbon monoxide, FVC: forced vital capacity; ITGV: intrathoracic gas volume; TLC: total lung capacity. There were no significant differences between the groups.
