  1. First number in every cell (D1-D9) specifies correlation coefficient, second number (N) – number of cases included into calculations.
  2. D1-D9 indicate changes of scale scores from baseline to follow-up for SF-36 PCS (D1), SF-36 MCS (D2), Physician Severity Assessment (D3), LEAS (D4), WOMAC Stiffness (D5), WOMAC Pain (D6), WOMAC Difficulty of Functioning (D7), KSS Functional Assessment (D8), KSS Knee Rating (D9).
  3. ** Correlation is significant at the 0.01 level (2-tailed).
  4. * Correlation is significant at the 0.05 level (2-tailed).
