Table 2A. Medial Tibial Subregions: Adjusted Odds Ratios (95% CI) for Baseline-to-2-year Cartilage Thickness Loss.

The tables show the odds ratios and associated 95% confidence intervals (CIs) for baseline-to-2-year cartilage thickness loss in the medial tibial (Table 2A) and medial weightbearing femoral (Table 2B) subregions, adjusted for age, gender, BMI, and tears in the other meniscal segments (covariate set A) and then adjusted for these factors and for meniscal extrusion (covariate set B).
