Values are expressed as mean ± standard error of the mean. ↓ represents a decreased value in response to vasodilator agent in comparison to value at rest. ↓↓ represents a highly significant decreased value that makes a separation between ethnic groups. ^aMean blood pressure is calculated from the reported diastolic and systolic values as 1/3 * systolic blood pressure + 2/3 * diastolic blood pressure. ND = Not determined.
