Statistical analysis
Statistical analyses were performed using SPSS version 21.0 (Chicago IL,
USA) . A p < 0.05 value was accepted as significant. For
normality testing, the Kolmogorov–Smirnov test was used. The
comparisons of variables between groups were performed using Student’s
t-test, Mann-Whitney U test and χ2 test. The
correlation between oxidative stress-related markers and liver function
tests was determined using the Spearman test or the Pearson test.
