Figure 2. Path model relating ethnicity and perceived discrimination to diastolic pressor responses to phenylephrine (PE). (A) The direct relationship between ethnicity and diastolic pressor responses to PE. (B) The indirect relationship between ethnicity and diastolic pressor responses to PE through perceived discrimination. After controlling for covariates (age, body surface area, cigarette smoking, baseline blood pressure), perceived discrimination mediated the relationship between ethnicity and diastolic pressor responses to PE.
