    Time frame: Baseline to Week 16

    The WOMAC index is comprised of 24 parameters grouped in 3 subscales (pain-5 questions, physical function -17 questions and stiffness - 2 questions), with 0-10 grading of each question. The scores for each subscale are summed up, divided by number of questions, and each subscale is reported using Numerical Rating Scale score of 0-10.
