Table 1.
Demographic data from the healthy participants (group1), patients with obstructive lung disease (group 2), and patients with restrictive lung disease (group 3).
Table 2.
Two consecutive computed tomography lung volume measurements in healthy participants (group1), patients with obstructive lung disease (group 2), and patients with restrictive lung disease (group 3).
Fig 1.
Comparisons between the two consecutive computed tomography (CT) lung volumes in healthy participants (group 1), patients with obstructive lung disease (group 2), and patients with restrictive lung disease (group 3).
Plots show the lung volumes from the first and follow-up CT scans. From left to right are the correlations from the two CT scans in (a) group 1 (n = 200, correlation coefficient (r) = 0.818, p<0.01), (b) group 2 (n = 100, r = 0.880, p<0.01), and (c) group 3 (n = 100, r = 0.910, p<0.01).
Fig 2.
Bland-Altman plots of the correlations between the two consecutive computed tomography (CT) lung volumes in healthy participants (group1), patients with obstructive lung disease (group 2), and patients with restrictive lung disease (group 3).
(a) in group 1, (b) group 2,(c) group 3. The dashed line indicates the mean bias, while the solid line indicates ±1.96 standard deviation.
