Table 1 Predominant type of emphysema and pulmonary fibrosis according to the ratings on high resolution computed tomography of the two observers

		Observer 2
		Type of emphysema
Observer 1			CLE = PSE	Paraseptal	Centrilobular
	Type of emphysema¹	CLE = PSE	2	0	0	2
		Paraseptal	0	23	0	23
		Centrilobular	0	2	26	28
			2	25	26
		Type of pulmonary fibrosis
			Typical UIP	Possible UIP	NSIP
	Type of pulmonary fibrosis²	Typical UIP	19	0	0	19
		Possible UIP	5	4	1	10
		NSIP	0	1	23	24
			24	5	24

¹The interrater reliability for the 2 observers was found to be Kappa = 0.929 (P < 0.001), 95%CI (0.757-1.000);

²The interrater reliability for the observers was found to be Kappa = 0.785 (P < 0.001), 95%CI (0.646-0.924). CLE: Centrilobular emphysema; PSE: Paraseptal emphysema; UIP: Usual interstitial pneumonia; NSIP: Nonspecific interstitial pneumonia.
