2.5. Statistical analysis

Statistical analysis was performed using IBM SPSS statistical software, version 19.0 (IBM SPSS, Chicago, IL, USA). Data were reported as the mean ± standard deviation (SD). Paired two-tailed Student’s t-test was used for body weight comparison. One-way analysis of variance (ANOVA) or Kruskal-Wallis test was employed for the comparisons between experimental groups. Post-hoc testing for ANOVA was performed using Tukey’s test. Mann-Whitney U test was used for post-hoc testing in Kruskal-Wallis analysis. All differences were considered statistically significant for a p value lower than 0.05 (p < 0.05).
