Serum and synovial fluid (SF) measures of the bone turnover markers osteocalcin and C-terminal telopeptides of type I collagen (CTX-I), cartilage derived CTX-II, joint-tissue-related growth factor TGF-β1, and the cytokine IL-6. Data are presented as mean ± standard deviation. Data with different letters are statistically different from each other (P <0.05) as measured by Kruskal-Wallis with multiple comparison of the mean ranks. P-values of the measures with significant differences (P <0.05) are shown in boldface text. §Trend (P ≤0.09).
