Note. Note. Displayed correlations correspond to the mean and variability outputs of the three baroreflex limbs in the full (All) sample and stratified by African Americans (AAs) and European Americans (EAs). For baroreflex sensitivity (BRS) and effectiveness (BI; shaded gray), limbs are denoted as: c = cardiac, v = vascular, m = myocardial. Bolded values denote significant differences between ethnicities on the corresponding correlation. Mean p refers to the significance test between AAs and EAs on mean output correlations. Variability p refers to the significance test between AAs and EAs on variability output correlation *p < .05. **p < .001.
