Table 4. Multivariable analysis of age, BMI, pain, and OA status.

The dataset was analyzed using multivariate analysis to examine the influence of these variables on fat pad volume. There was an association of fat pad volume with age, independent of BMI, pain and knee OA status, which was statistically significant at baseline, 3, 6, and 12 months. Results show parameter estimates and p values.
