COR R E C T I ON Open Access Estimation of minimally important differences in EQ-5D utility and VAS scores in cancer A Simon Pickard 1* , Maureen P Neary 2 , David Cella 3 Correction We wish to correct a mistake in the abstract and con- clusion of our published paper [1]. In the a bstract and conclusion, the MID for EQ-VAS score should be reported as 7 rather than 0.07. EQ-VAS scores range from 0 to 100, while EQ-5D index-based scores are anchored by 0 (dead) and 1 (perfect health). The specific wording in the conclusion of the abstract should read “Important differences in EQ-5D utility and VAS scores were similar for all cancers and lung cancer, with the lower end of the range of estimates closer to the MID, i. e. 0.08 for UK-index scores, 0.06 for US-index score s, and 7 for VAS scores.
