Relationship between high BP counts and mean SBP/DBP in the simulated HBP cohort (when K = 24; panel A for SBP and panel B for DBP). There were tight linear associations between high BP counts and mean SBP/DBP. As SDs increased, the strength of the association decreased, and the width of the 95% PIs increased. When the SD was 5, high BP counts ≤ 9 indicated controlled SBP/DBP, and high BP counts ≥ 15 indicated uncontrolled SBP/DBP with ≥ 95% confidence. When SD > 5, high BP counts ≤ 8 indicated controlled SBP/DBP, and high BP counts ≥ 16 indicated uncontrolled SBP/DBP with ≥ 95% confidence. Each dot represents a series of 24 simulated HBPs, and the dots in a panel represent 100 series of simulated HBPs at an SD level. The blue solid lines indicate the linear regression fits between high BP counts and mean SBP/DBP, and the red ribbons indicate the 95% PI of the mean SBP/DBP. The gray dotted lines indicate the smallest and the largest high BP counts outside the upper and lower limits of the 95% PIs, respectively. High SBP/DBP was defined as an SBP ≥ 135 mmHg/DBP ≥ 85 mmHg. PI prediction interval, SBP systolic blood pressure, DBP diastolic blood pressure, SD standard deviation.
