FIGURE 2:

Subjects 18–70 years old showing by quadratic prediction plots an inverse relationship between V_glom and N_glom for African Americans and whites in which the V_glom of hypertensive subjects are larger than that of non-hypertensive subjects throughout the range of N_glom. Multivariable robust regression (V_glom-dependent variable): African Americans, coefficient N_glom = −2.86e−06, P < 0.001, coefficient hypertension = 1.71, P < 0.001; whites, coefficient N_glom = −3.24e−06, P < 0.001, coefficient hypertension = 1.14, P = 0.01.
