Ten-year absolute risk of combined cardiovascular events in relation to 24-hour blood pressure (A and B) at different levels of systolic and diastolic average real variability over 24 hours (ARV24). The analyses were standardized to the distributions (mean or ratio) of cohort, sex, age, 24-hour heart rate, body mass index, smoking and drinking, serum cholesterol, history of cardiovascular disease, diabetes mellitus, and treatment with antihypertensive drugs. Plotted values of 24-hour blood pressure span the 5th to 95th percentile interval. The continuous risk functions correspond with the 5th, 25th, 50th, 75th and 95th percentile of ARV. P-values are for the independent effect of ARV (Parv) and 24-hour blood pressure (Pbp). np and ne indicate the number of participants at risk and the number of cardiovascular events.
