Biochemical Characterization of Early Osteoarthritis in the Ankle
Figure 2
Increasing intra-articular levels of aggrecan are observed with progress of OA measured by a functional score of the ankle (AOFAS). Results of the polynomial regression analysis, the Spearman correlation, and the post hoc statistics (Kruskal-Wallis H-Test) are indicated for absolute aggrecan levels and concentrations in relation to the total protein content (TPC) on the bottom. Polynomial regression with degree of 2 gives an for absolute and for relative concentrations; values are shown with ±SEM.
