  1. a Utilities are expressed in median scores (interquartile range); b For NRS (Pain), NRS (General Health) and HAQ-DI: a worse health outcome was defined by the > median value of each outcome measure; c For the SF-36 and SF-6D: a worse health outcome was defined by the ≤ median value of each outcome measure; d Median values for the NRS (Pain), 4; for the NRS (General health), 5; for the SF-36 PCS, 40.05, MCS, 40.99; for the SF-6D, 0.63; for the HAQ-DI, 0.88; e NRS = numerical rating scale.
