All data are shown as mean ± SEM for 5-10 observations per group. ANOVA indicated that body weight was influenced by sex (P<0.001), age (P<0.001) and the interaction of age and sex (P<0.001). Liver weight was influenced by age (P<0.001), sex (P<0.001) and the age x sex interaction (P<0.001). Liver weight as a percentage of body weight was influenced by sex (P=0.034), age (P<0.001).
