There were significant relationships between joint space width (= 0.003), pyridinoline (= 0.034) and TIMP-1 (= 0.017) determined with the Kruskal–Wallis test. Bars indicate maximum and minimum values within the observation range. values are shown in each panel; N.S. indicates not significant. CRP, C-reactive protein; MMP, matrix metalloproteinase; TIMP, tissue inhibitor of metalloproteinases.
