Values are means ± SD. Slice locations used for the calculation of regional (apex, mid, and base) or global values are defined in Figure 1.

^{^*}

P > 0.05, global and regional average values are not significantly different;

^{^†}

P < 0.001, global values are less than average regional values;

^{^‡}

P < 0.05, group means are different (ANOVA);

^{^§}

P > 0.05, group means are not different (ANOVA).
