Comprehensive Analysis of Transcriptome Sequencing Data in the Lung Tissues of COPD Subjects

Table 1

Demographics of COPD subjects and control subjects with normal lung function.

	COPD subjects	Control subjects	value
Male, (%)	98 100.0	91 100.0
Age, years	67.5 ± 6.4	60.9 ± 9.5	<0.0001
Smoking (py)	48.0 ± 22.0	35.2 ± 17.2	<0.0001
FEV1, %	71.9 ± 13.4	91.0 ± 12.4	<0.0001
FEV1/FVC	57.1 ± 7.8	74.8 ± 4.3	<0.0001
DLCO, %	77.4 ± 13.8	92.8 ± 13.2	<0.0001

COPD: chronic obstructive pulmonary disease; DLCO: diffusing capacity of the lung for CO₂; pack-years; FEV1: forced expiratory volume in 1 second.
Unless otherwise stated, the mean ± standard deviation is shown.
