Table 2.

Correlation was found between body weight and the grade of osteoarthritis in the hip and knee joint in the total population. Otherwise, no correlation was found between body weight and the grade of osteoarthritis of the osteoarthritis-positive mice versus the osteoarthritis-negative mice. The BMD showed no correlation.
