WOMAC = Western Ontario and McMaster Osteoarthritis Index, BW = Body VAS = Visual Analog Scale

Data at 4-weeks is statistically significantly different (p ≤ 0.05) at 4-weeks compared to baseline

Data is statistically significantly different (p ≤ 0.05) between responders and non-responders at 4-weeks
