Values are mean ± SD. In the same line, different superscript letters refer to significant differences tested by Duncan’s multiple range test (p < 0.05). The significance is noted by asterisks as follows: *—statistically significant differences at p-value < 0.05; **—statistically significant differences at p-value < 0.01; ns—not significant.
