Table 5 Changes observed in the OHS, EQ-5D-5 L, and WOMAC questionnaires at 6 months of the follow-up period, in patients that reported health condition changes

From: Cross-cultural adaptation and validation of the Spanish version of the Oxford Hip Score in patients with hip osteoarthritis

  1. Final scores were subtracted from basal scores in the OHS and EQ-5D-5 L, and the opposite happened in the WOMAC. This way, positive outcomes always indicate improvement
