Risk of stroke and heart failure by nocturnal blood pressure dipping status and 24-hour systolic blood pressure control status. Values are adjusted for age, sex, body mass index, smoking, alcohol intake, diabetes, dyslipidemia, prevalent cardiovascular disease, use of antihypertensive drugs, bedtime dosing, and office and 24-hour systolic blood pressure. CHF indicates congestive heart failure; HR, hazard ratio; UC 24hBP, uncontrolled 24-hour blood pressure (24-hour systolic blood pressure >130 mm Hg); and WC 24hBP, well-controlled 24-hour systolic blood pressure (24-hour systolic blood pressure ≤130 mm Hg).
