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 Kolmogorov‐Smirnov 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.
