Risk curves for cardiovascular mortality with blood pressure categories measured at the health survey and the cardiovascular observation study

(A and B) Curves are reflecting the risk of cardiovascular mortality during the follow-up of the cardiovascular observation study (OS) associated with blood pressure at OS or the health survey (HS). Curves are calculated according to loess (locally weighted scatterplot smoother) with 95% confidence intervals. BP categories were built using systolic and diastolic measurements according to ACC/AHA guidelines (A) and ESC/ESH guidelines (B), which are applying different cutoffs. The approximate crossing point between OS and HS-derived curves is indicated by a dashed line.
