Figure 7:

The predicted probability of worsening of KL score over 8 years (orange), and joint space narrowing (JSN) change over 8 years (green). Modeled values are based on logistic regression models with baseline cartilage T₂ Z-score in the medial femur as a predictor. For both outcomes, the probability of incidence/progression increases as a function of cartilage T₂ Z-score in the medial femur. (Modified from (65).) Calculation of T₂ Z-score may help identify patients at risk for OA progression who would benefit from lifestyle intervention.
