Outcome Measures

Primary Outcome Measures

  1. Change From Baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Pain Subscore Over 12 Weeks [Baseline over 12 weeks]

    Observed VAS of 100 mm; 0 mm meaning no pain; 100 mm meaning extreme pain. Change in score from baseline over 12 weeks was analyzed using a repeated measures Analysis of Covariance (ANCOVA) model.

Secondary Outcome Measures

  1. Change From Baseline in WOMAC Pain Subscore at Weeks 12 and 26 [Baseline, Weeks 12 and 26]

    Observed VAS of 100 mm; 0 mm meaning no pain; 100 mm meaning extreme pain. Changes in score from baseline at Weeks 12 and 26 were analyzed using a longitudinal model.

  2. Change From Baseline in WOMAC Physical Function Subscore at Weeks 12 and 26 [Baseline, Weeks 12 and 26]

    Observed VAS of 100 mm; 0 mm meaning no difficulty; 100 mm meaning extreme difficulty. Changes in score from baseline at Weeks 12 and 26 were analyzed using a longitudinal model.

  3. Change From Baseline in WOMAC Stiffness Subscore at Weeks 12 and 26 [Baseline, Weeks 12 and 26]

    Observed VAS of 100 mm; 0 mm meaning no stiffness; 100 mm meaning extreme stiffness. Changes in score from baseline at Weeks 12 and 26 were analyzed using a longitudinal model.

  4. Change From Baseline in WOMAC Total Score at Weeks 12 and 26 [Baseline, Weeks 12 and 26]

    WOMAC total score was the mean of WOMAC pain, physical function and stiffness subscores and ranges from 0 to 100 mm, where higher scores indicated worse response. Changes in WOMAC total score from baseline at Weeks 12 and 26 were analyzed using a longitudinal model.
