Partial correlations between brachial and central blood pressure components with carotid-femoral pulse-wave velocity, augmentation index, augmentation pressure, and carotid-radial pulse-wave velocity after adjustment for age, sex, height, and heart rate

	Brachial systolic BP	Brachial PP	Brachial diastolic BP	Central systolic BP	Central PP	Mean arterial pressure	PP amplification
Carotid-femoral PWV	0.07	0.02	0.13	0.14	0.06	0.17^a	–0.16^a
Augmentation index@HR75^c	–0.28^b	–0.35^a	0.24^b	–0.04	–0.22^b	0.22^b	–0.56^b
Augmentation pressure	–0.38^b	–0.43^b	0.21^b	–0.14^a	–0.27^b	0.16^a	–0.64^b
Carotid-radial PWV	–0.13	–0.19^b	0.20^b	–0.09	–0.20^b	0.06	0.06

Values are partial r coefficients.

Abbreviations: PWV, pulse wave velocity; PP, pulse pressure; BP, blood pressure; augmentation index@HR75, augmentation index adjusted to a heart rate of 75 bpm for each subject.^a P < 0.05; ^b P < 0.01.

^cNote: because augmentation index@HR75 is already corrected for heart rate, heart rate was not entered as a covariate in the partial regression for this variable only.
