FIGURE 6.

Duration of attacks received, social defeat posture, escape behaviour and immobility behaviour during exposure to aggressor ICR mice. No significant difference was found in durations for attacks received, defeat posture, immobility behaviour and escape behaviour between wild‐type mice and FGF21‐deficient mice. The time spent for immobility behaviour was increased during the fifth social defeat stress compared to during the first social defeat stress. The number of wild‐type mice and FGF21‐deficient mice was 6 and 8, respectively. ††P < 0.01, day 1 vs day 5, two‐way repeated measures ANOVA
