SF-6D disutility scores in relation to 15-scale radiographic knee OA definition. 15-scale radiographic knee OA (combination of K-L grades in both knees). Disutility of the best health state possible (K-L grade 0;0) is set as the horizontal reference line (dotted). Other horizontal lines (dotted) are set in 0.027 point intervals representing 1.0 MID (minimally important difference). Error bars are 95% confidence intervals. The mean difference is significant at the 0.05 level (*) in comparison to the best health state (K-L grade 0;0)
