Notes:
a–e
p is significant at 0.05. For a particular variable, mode means with different superscript are significantly (P > 0.05) different. Mode means with same superscripts are not significantly (P > 0.05) different. When only one contrast is significant, one of the cell means has no superscript attached. The pair of cell means that is significant has different superscripts.
Abbreviations: ANOVA, analysis of variance; BMI, body mass index; BP, blood pressure; DBP, diastolic blood pressure; HR, heart rate; SBP, systolic blood pressure; SD, standard deviation.
