2.4 Statistical analyses
Statistical analysis was performed using the SPSS ver. 26.0 software
(SPSS, Inc., Chicago, IL, USA). Quantitative data (such as WBC, L%,
LYM, ALT, AST, GGT, UREA, CREA) with normal distribution or approximate
normal distribution were expressed as mean ± standard deviation. T test
or Mann-Whitney test was used to compare the data between the two
groups. Comparing the data among multiple groups, the analysis of
variance or Kruskal Wallis test is adopted. A P -value <
0.05 was considered to be statistically significant.
