Continuous data are presented as mean ± standard deviation and categorical data are presented as number (percentage). pSBP: peripheral systolic blood pressure; pDBP: peripheral diastolic blood pressure; pMBP: peripheral mean blood pressure; pPP: peripheral pulse pressure; cSBP: central systolic blood pressure; cDBP: central diastolic blood pressure; cMBP: central mean blood pressure; cPP: central pulse pressure; HR: heart rate; bpm: beats per minute; pAIx: peripheral augmentation index; cAIx: central augmentation index; cAIx-75: central augmentation index corrected for heart rate; PWV: pulse wave velocity. * Student t-test for independent samples. ** ANCOVA model adjusted for age and BMI. *** Chi-square test. a According to the ESC/EHA guidelines, PWV > 10 m/s is considered to represent an end-organ damage [40].
