Difference plot comparing the mean cholesterol levels of each normalized fraction from the DGUC for the macroalbuminuric group (n = 24) versus the microalbuminuric group (n = 80). If the difference is positive, the macroalbuminuric cholesterol value is greater than the microalbuminuric value. │, Standard fractions. For a fractional difference, , P ≤ 0.05; 0.05 < P ≤ 0.10; ●, not significant.
