Modeling for selection of cases and controls. The base population used in modeling (n = 719) were plotted with their observed systolic blood pressure (SBP) and their expected SBP as predicted by multiple regression. Subjects in red are hypertensive above the mean and were designated as cases (n = 170). Subjects in blue are nonhypertensive below the mean and were designated as controls (n = 277)
