All data reported as mean (SD). cDBP indicates central diastolic blood pressure; cSBP, central systolic blood pressure; DBP, diastolic blood pressure; HR, heart rate; PR, PR interval; QRSd, QRS duration; QT, QT interval; QTcB, Bazett's corrected QT interval; QTcF, Fridericia's corrected QT interval; SBP, systolic blood pressure.
a
P value for analysis of variance adjusted for subject variability.
b
No statistically significant difference was noted between drink A and drink B for any parameter.
c
Statistically significant difference between drink A and placebo.
d
Statistically significant difference between drink B and placebo.
