Ca, calcium; ACE-I, angiotensin-converting enzyme inhibitor; ARB, angiotensin II receptor blocker; sBP, systolic blood pressure; dBP, diastolic blood pressure; MAP, mean arterial pressure; PR, pulse rate; HTN, hypertension; BP, blood pressure. Values are presented as medians and interquartile ranges (IQRs) or numbers with percentages in parentheses. BP drop rate was defined as (daytime sBP-nighttime sBP)/daytime sBP. The bold values indicate statistically significant.
