Krill oil and fish oil reduce clinical arthritis signs in mice. A) Clinical arthritis scores in DBA/1 mice following induction of collagen induced arthritis with collagen boost on study day 47. B) Hind paw thickness (mm) measurements in DBA/1 mice following induction of collagen induced arthritis on study day 47. Data represents mean values ± SEM (n = 13-14). For mice that were culled due to arthritis severity, the values for the last measurement of clinical arthritis scores and hind paw thickness were used for calculations throughout the rest of the study. * Significantly different from control group (P < 0.05).
