The receiver operator curve of adult cardiovascular risk for individuals with elevated blood pressure in childhood by the number of times abnormal BP was observed during childhood when subjects were aged 6–18 years. a The receiver operator curve of adult hypertension for individuals with elevated blood pressure in childhood. b The receiver operator curve of adult arterial stiffness for individuals with elevated blood pressure in childhood. c The receiver operator curve of adult left ventricular hypertrophy for individuals with elevated blood pressure in childhood. Blue line: the receiver operator curve of adult cardiovascular risk for individuals with one abnormal blood pressure measurement observed during childhood (adjusted for age, sex, family history of hypertension, heart rate, and height at baseline); Green line: the receiver operator curve of adult cardiovascular risk for individuals with two abnormal blood pressure readings observed during childhood (adjusted for age, sex, family history of hypertension, heart rate at baseline, and weight at follow-up); Orange line: the receiver operator curve of adult cardiovascular risk for individuals with three abnormal blood pressure measurements observed during childhood (adjusted for age, sex, family history of hypertension, heart rate, and body mass index at baseline)
