Change From Baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Pain Subscale Score at Week 8: ITT PopulationPrimary· Baseline, Week 8
The WOMAC pain subscale is a 5-item questionnaire used to assess the amount of pain experienced due to osteoarthritis (OA) in the index joint (knee/hip) during past 48 hours. It is calculated as the mean of the scores from the 5 individual questions scored on a numerical rating scale (NRS) of 0 to 10, where higher scores indicate higher pain. Total score range for WOMAC pain subscale score is 0 to 10, where higher scores indicate higher pain.
