Note: *p < 0.05, **p < 0.01; The ANOVA test was applied when variance homogeneity was satisfied (F-measure); non parametric rank test was applied when missing variance (Z-measure or Chi square value)
^aMean values were significantly different from those of the first group (p < 0.05)
^bMean values were significantly different from those of the second group (p < 0.05)
