The pain in subjects with osteoarthritis was measured using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscale score. The WOMAC pain subscale score is calculated as the average of the visual analogue scale (VAS) scores from 5 pain subscale questions. Subjects mark the VAS, which is a horizontal line 100 mm in length, with a single vertical line to indicate their pain level over the last 24 hours, with 0 mm representing "No Pain" and 100 mm representing "Extreme Pain". The WOMAC pain subscale score difference is calculated as the WOMAC pain subscale score assessed at Week 12 minus the WOMAC pain subscale score assessed at baseline.

Pain, stiffness, and function in subjects with osteoarthritis were measured using the Western Ontario and McMaster Universities (WOMAC) Index, which is a 24-item questionnaire. The total (composite) WOMAC score is calculated as the average of the mean visual analogue scale (VAS) scores from the questions in the pain, stiffness, and function subscales. Subjects mark the VAS, which is a horizontal line 100 mm in length, with a single vertical line to indicate their response to each of the questions, with 0 mm representing "No Pain, Stiffness, or Difficulty" and 100 mm representing "Extreme Pain, Stiffness, and Difficulty". The total (composite) WOMAC score difference was calculated as the total (composite) WOMAC score assessed at Weeks 2, 6, and 12 minus the total (composite) WOMAC score assessed at baseline.
The pain intensity is assessed using a visual analogue scale (VAS), which is a horizontal line 100 mm in length. Subjects mark the VAS with a single vertical line to indicate their current pain level, with 0 mm representing "No Pain" and 100 mm representing "Worst Pain Imaginable". The VAS pain intensity difference is calculated as the average of the VAS pain intensity scores at Weeks 2, 6, and 12 minus the VAS pain intensity at baseline.
