Notes: HIV group-included variables: brachial SBP, brachial DBP, and age (R² = 0.80; P < 0.05). Controls group-included variables: male sex, brachial SBP, brachial DBP, and BMI (R² = 0.86; P < 0.05).

Abbreviations: Aix, augmentation index (corrected for heart rate); HIV, human immunodeficiency virus; SBP, systolic blood pressure; DBP, diastolic blood pressure; BMI, body mass index
