Figure 4. Relationship of osteoarthritic changes in the index and contralateral stifles.

Figure 4

(A) Bivariate histogram of radiographic synovial effusion grade in index and contralateral stifles. (B) Bivariate histogram of osteophytosis grade in index and contralateral stifles. Severity of osteophytosis (SR = 0.39, p<0.0005), but not synovial effusion (SR = 0.17, p = 0.13) in the index and contralateral stifles were correlated.
