Relationship between systolic blood pressure (SBP) and consultations. (a) SBP and primary physician consultation rate of hypertensive patients. The consultation rate = 1-exp(-(SBP-a)×b) (a = alarming SBP level, above which patients should be concerned; b = the accessibility factor to a primary physician). The thick black (a = 130, b = 0.05), thin black (a = 140, b = 0.03), and thick gray (a = 150, b = 0.02) lines represent ideal, optimistic, and realistic situations, respectively. (b) SBP and probability of consultation with a primary physician. The probability equals the product of the probability density in the sample population and the consultation rate.
