- Data are presented as mean ± standard deviation or n (%)
- BMI body mass index, OA osteoarthritis, NRS numerical rating scale
- aStage A: Kellgren–Lawrence (KL) grading score for hip OA stage (Early stage); ankle OA stage (Stage 1/ Stage 2); shoulder OA and elbow OA (Grade 2). Stage B: KL grading score for hip OA stage (Advanced stage); ankle OA stage (Stage 3); shoulder OA and elbow OA (Grade 3)
- bAverage of 7 days prior to Week 0 by the 0–10 numerical rating scale for pain intensity: 0 indicates no pain, and 10 indicates the worst pain
