Data are mean ± SD. ANOVA columns represent results from the two-way analysis of variance for age and gender including the interaction term.

AP = augmentation pressure; AIx = augmentation index; cPP = central pulse pressure; csystolic BP = central systolic blood pressure; HR = heart rate; MAP = mean arterial pressure; pdiastolic BP = peripheral diastolic blood pressure; PP Amp = pulse pressure amplitude; pPP = peripheral pulse pressure; psystolic BP = peripheral systolic blood pressure.
