FIGURE 4:

Subjects 18–70 years old demonstrating by linear regression the relationships between V_glom and log 2 of percent glomerulosclerosis among hypertensive and non-hypertensive subjects for African Americans and whites. The V_glom of hypertensive subjects was larger than that of non-hypertensive subjects (P < 0.001). The enlargement was present throughout the range of glomerulosclerosis with the difference being most pronounced with early, or mild, glomerulosclerosis. With more advanced glomerulosclerosis, there was a slight but not significant tendency toward the convergence of V_glom in both races (African Americans hypertension, r = −0.152, P = 0.23; non-hypertension, r = 0.105, P = 0.26); whites hypertension, r = −0.047, P = 0.94; non-hypertension, r = 0.089, P = 0.74).
