Relative importance of the EQ-5D five dimensions among patients with chronic diseases in South Korea – a comparison with the general population preference weights

Table 5 The relative importance of the EQ-5D dimensions – difference between patient and general population valuations

	Patient VAS model			EQ-5D general population TTO model
	Level 2	Level 3	Mean	Level 2	Level 3	Mean
Mobility	0.994	0.745	0.869	1.758	1.951	1.855
Self-care	0.856	0.558	0.707	0.842	0.635	0.739
Usual activities	0.846	0.561	0.704	0.934	0.971	0.953
Pain/discomfort	0.878	1.596	1.237	0.678	0.705	0.691
Anxiety/depression	1.426	1.541	1.483	0.788	0.738	0.763

Note: The relative importance for each level of each dimension was calculated by dividing the corresponding coefficient from Table 4 (model 3) by the average of the five coefficients at the same level in the same model. For the EQ-5D general population TTO model, the model coefficients were taken from the study by Lee et al. (2009) [26] to calculate the relative importance of the EQ-5D dimensions and levels
