2.5. Statistical methods
The data in the tables are expressed as mean SD, and those in the figures are expressed
as mean SE. Comparison of differences between values before and after treatment in the
same group was determined by t-test and between different groups by ANOVA and Post Hoc
LSD’s test in multiple comparisons. P values less than 0.05 were considered significant.
SPSS 10.1 package was used.
