(A) Comparison of maximum mean WOMAC improvement before 3 months post-treatment compared to 6 months post-treatment for Group 1 and placebo patients. Vertical bars indicate 95% confidence interval. Comparison of means between Group 1 and placebo was p = 0.02 at ≤3 months and p =< 0.0001 at 6 months. (B) Comparison of maximum mean VAS improvement before 3 months post-treatment compared to 6 months post-treatment for Group 1 and placebo patients. Vertical bars indicate 95% confidence interval. Comparison of means between Group 1 and placebo was p =0.02 at ≤3 months and p = 0.001 at 6 months.
