| Physician NRS (0–10) | 2.17 (0.93) | 5.66 (1.47) | <0.001 | 2.84 (2.78 to 2.89) |
| WOMAC function (0–100) | 16.32 (7.79) | 47.35 (12.73) | <0.001 | 2.94 (2.45 to 3.43) |
| Hip OA | ||||

↵* p Value was obtained by Wilcoxon's non-parametric comparison of means.
NRS, numerical rating scale; OA, osteoarthritis; PASS+, patient acceptable symptom state achieved; PASS-, PASS not achieved; WOMAC, Western Ontario and McMaster Universities osteoarthritis index.
