Lung function test results.

	COPD patients ()	Controls ()	value
FEV1%	49 (35–72)	107 (80–120)	<0.001
FVC%	64 (56–81)	103 (87–120)	0.001
FEV1/FVC ratio	60 (45–70)	79 (75–83)	<0.001
RV%	165 (141–204)	105 (79–139)	0.045
TLC%	112 (99–123)	98 (94–112)	NS
RV/TLC ratio	56 (50–69)	37 (28–45)	0.001
DLCO%	65 (27–94)	82 (72–96)	NS
KCO%	84 (43–110)	90 (77–106)	NS

Values are expressed as median (interquartile range); value < 0.05 as statistically significant; FEV1 = forced expiratory volume in 1 second; FVC = forced vital capacity; TLCOc = transfer factor of the lung for carbon monoxide; KCO = transfer coefficient; RV = residual volume; TLC = total lung capacity.
