^{a}Data are expressed as mean (SD) and compared by use of one-way ANOVA unless specified otherwise. | ||||

^{b}Data are expressed as median (interquartile range) and compared by use of the Kruskal-Wallis test. | ||||

^{c}P < 0.001, ^{d} P < 0.05, compared with group I by use of the Bonferroni post hoc test. | ||||

^{e}P = NS, ^{f} P < 0.001, and ^{g} P < 0.05, group II versus group III, by use of Bonferroni post hoc analysis. | ||||
