Fig. 1From: Associations between systemic bone mineral density and early knee cartilage changes in middle-aged adults without clinical knee disease: a prospective cohort studyAssociation between baseline systemic bone mineral density (BMD; g/10 cm2) and annual percentage loss in tibial cartilage volume adjusted for age, gender, body mass index, strenuous physical activity, and respective tibial bone area. a Annual percentage loss in lateral tibial cartilage volume in relation to spine BMD (r = 0.24, p = 0.01) and total hip BMD (r = 0.28, p = 0.001); b Annual percentage loss in medial tibial cartilage volume in relation to spine BMD (r = 0.03, p = 0.75) and total hip BMD (r = 0.04, p = 0.53) Back to article page
