	The hip condition is “much worse” N = 53		The hip condition is “slightly worse” N = 78		The hip condition is “slightly better” N = 34		The hip condition is “much better” N = 60

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
