Figure 4. Association Between Serum Collagen Type-II Cleavage Product to Collagen Type-II C-Propeptide [C2C:CPII] Ratios at the Six-Month Follow-up Exam and External Knee Adduction Moment Limb Symmetry Index (KAM-LSI).

Figure 4

Lower vGRF LSI (X-axis) at the six-month follow-up exam associated with higher serum concentrations of C2C:CPII ratios (Y-axis) collected at the initial presentation exam (r=− 0.5; P= 0.04) yet this association was not significant after controlling for walking speed (partial r =− 0.24; P= 0.36).
