 DBP6.84 ± 6.917.24 ± 8.210.845
 BP pattern (dipper/nondipper)5/227/200.513

dippers were defined as those with a >10% decline in both systolic and diastolic blood pressure
Note: day-night BP difference calculated as day time BP minus night time BP, and relative night time decline calculated as: (day time BP – night time BP) ÷ day time BP × 100%
APA, aldosterone-producing adenoma; BP, blood pressure; DBP, diastolic blood pressure; EH, essential hypertension; SBP, systolic blood pressure
