Key: Since non-linear terms do not have a single odds ratio, those were omitted from the table, though p-values from a likelihood ratio test were included to display significance. P-values bolded were statistically significant at the 0.05 level. AC=articular cartilage; BTB=bone-patellar tendon-bone;Tx=treatment.
