  • The tables show the OR and associated 95% CI for baseline to 2-year cartilage thickness loss in the medial tibial and medial weight-bearing femoral subregions, adjusted for age, gender, body mass index and tears in the other meniscal segments (covariate set A) and then adjusted for these factors and for meniscal extrusion (covariate set B).
