The hypertensive cut-off in HBP by HBPM was determined in Japanese pregnant women. (A) Optimizing the polynomial of systolic HBP that induces the hypertensive boundary value by HBPM. By the polynomial equation of mean +3 SD, systolic HBP at 35 weeks gestation equal to non-pregnant was 135 mmHg, the current reference value for non-pregnant hypertension of HBPM. Polynomial of mean +3 SD was considered optimal. (B) Optimization of polynomial of diastolic HBP that induces the hypertensive boundary value by HBPM. By polynomial of mean +2SD, diastolic HBP at 38 weeks gestation equal to non-pregnant was 85 mmHg, the current standard for non-pregnant hypertension by HBPM. Thus, polynomial of mean +2 SD was considered optimal.
