Data were presented as mean ± standard error of the mean (SEM). TAG liver data were transformed
to square root values to achieve normality before significance testing. One-way analysis of variance
(ANOVA) was used, followed by a post hoc Tukey-Kramer significant differences test for multiple
comparisons among the groups. Differences were considered significant when p < 0.05. A simple
association between two variables was calculated using Pearson’s correlation coefficient. All statistical
analysis was performed using SPSS software (version 17.0, SPSS Inc., Chicago, IL, USA)
