The Shapiro-Wilk’s test was used to test the normality assumption of the data. Levene’s test was used for the variance in homogeneity assumption. The values were expressed as the mean ± standard deviation, median (25–75th percentile), or n (%). The parametric comparisons were made using a t-test or z-test, and the nonparametric comparisons were made using the Mann-Whitney U test. All of the comparisons were made with the PASW Statistics 18 program, and a p value of < 0.05 was considered to be statistically significant
