Figure 2From: Evaluation of bone marrow lesion volume as a knee osteoarthritis biomarker - longitudinal relationships with pain and structural changes: data from the Osteoarthritis InitiativeScatter plot of WOMAC pain change by bone marrow lesion (BML) volume change stratified by tertiles (colors). Tertiles, based on baseline BML volume, had average baseline total knee BML volumes of 0.6 ± 0.2 cm3, 1.6 ± 0.5 cm3, and 5.5 ± 2.9 cm3, respectively.Back to article page
