Statistical Analysis
Data were analyzed on SPSS 17.0 software (IBM Statistics for Windows
version 17, IBM Corporation, Armonk, New York, USA). Distribution of
continuous data was assessed using the KolmogorovāSmirnov test.
Quantitative data were expressed as mean ± standard deviation (SD) and
median range (maximum-minimum) values in tables. Categorical data were
expresses number (n) and percentage. Intergroup comparisons were
performed usingrepeated measure ANOVA followed by the Bonferroni test.
Time-dependent changes were compared within and between groups. When
theMauchly test was significant, normality and equality of variance were
not violated, and the Greenhouse-Geisser adjustment was performed to
determine the statistical significance of the factors.p values less than
0.05 were regarded as statistically significant.
