  • Values are means ± s.d. for each variable, indicated by loading cohort; N=8 for each diet.

    O-diet rabbits develop elevated bone-density levels along the articular surface, subchondral region and external cortical surface of the condylar neck. Asterisks indicate significant differences, *P<0.05, **P<0.01; Mann—Whitney U-test.
