The total score of the pain subscale for each patient is normalized and expressed on a 0 to 4 scale. Higher scores represent higher levels of pain (worse outcome), whereas lower scores represent lower levels of pain (better outcome). Missing data were imputed. |

Outcome results
Change From Baseline in WOMAC Pain Subscale at Week 12
The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Pain subscale consist of five items, each ranging from 0 to 4, making the total Pain subscore 0 to 20. The total score of the pain subscale for each patient is normalized and expressed on a 0 to 4 scale. Higher scores represent higher levels of pain (worse outcome), whereas lower scores represent lower levels of pain (better outcome). Missing data were imputed.
