Table 2 Analysis of the interobserver agreement of Total Severity Score-based assessments of chest computed tomography scans. The table presents the κ and intraclass correlation coefficient values for the overall assessment as well as for the assessments of individual lung lobes.

		Total Severity Score
		Right lung			Left lung		Total
		Upper lobe	Middle lobe	Lower lobe	Upper lobe	Lower lobe	Total
κ		0.938	0.945	0.937	0.937	0.938	0.944
		<0.001	<0.001	<0.001	<0.001	<0.001	<0.001
95% CI	UL	0.956	0.959	0.951	0.954	0.954	0.948
95% CI	LL	0.922	0.934	0.923	0.919	0.923	0.941
ICC (3, k)		0.944	0.947	0.944	0.944	0.944	0.948
		<0.001	<0.001	<0.001	<0.001	<0.001	<0.001
95% CI	UL	0.946	0.948	0.946	0.946	0.946	0.949
95% CI	LL	0.940	0.946	0.940	0.940	0.940	0.947
CI – confidence interval; ICC – intraclass correlation coefficient; LL – lower limit; UL – upper limit.
