  1. P-values were assessed with analysis of covariance (ANCOVA) using the number of co-localized factors in the medial compartment at baseline as the dependent variable. Statistically significant P-values are in bold. *Co-localized factors: 0 = neither bone marrow lesions nor meniscal extrusion, 1 = either meniscal extrusion or bone marrow lesions, 2 = meniscal extrusion and bone marrow lesions. MRI, magnetic resonance imaging.
