  1. Abbreviations: k = constant determining the slope of the exponential curve between systolic blood pressure and cardiovascular incidence rate; l = constant related to absolute value of cardiovascular incidence rate of 100; m = constant determining the slope of the exponential curve to be e0/l of 140; a = an alarming SBP of 130, 140, 150, and 160 mm Hg, above which patients should be concerned about their BP; b = an accessibility factor to a primary physician of 0.05, 0.03, 0.02, and 0.01; c = the target SBP level of 130, 140, 150, and 160 mm Hg; d = adherence for reaching the target SBP level of 0.5, 0.6, 0.7, and 0.8; e = SBP level of 140, 150, 160, or 180 mm Hg from which administration of antihypertensive medications was initiated.
