Regression analysis of post-treatment changes for pain and activity level with regard to MRI-proven cartilage damage level and common epidemiological data. Dependent variables are Change of VAS (visual analogue scale) and Change of WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index). OLS regression coefficients with p values in parentheses (*p ≤ .05, **p ≤ .01, ***p ≤ .001 two-tailed)
