Health state utility measured in both EQ-5D and PROPr, dependent on condition. The dashed line at HSU = 0.9 refers to the estimated population average of the EQ-5D [33,34,35,36,37]; the dashed-dotted line at HSU = 0.5 refers to the estimated population average of the PROPr [18, 19]; SLE = systemic lupus erythematosus, PSPD = persistent somatoform pain disorder
