Table 2:
Blood pressure status and characteristics by age for 3550 person-visits contributed by 902 participants. Hypertensive status was defined using clinic data, based on current American Academy of Pediatrics (AAP) guidelines12. Clinic BP was classified as normal, elevated, stage 1 hypertensive BP, or stage 2 hypertensive BP.
