From: An improved method for estimating low LDL-C based on the enhanced Sampson-NIH equation
Mean absolute difference of estimated LDL-C equations at different intervals for independent variables. Mean absolute difference (MAD) of LDL-C when compared against BQ LDL-C from patients in the validation dataset (N = 12,210) is shown for the F LDL-C (purple line), eM LDL-C (red line), S LDL-C (green line) and eS-LDL-C (orange line) equations for the indicated TG intervals (A), nonHDL-C intervals (B), HDL-C intervals (C), and apoB intervals (D). The insets shows a close-up for low TG and low nonHDL-C samples. The number of samples within each interval is indicated on the X-axis. Solid black line corresponds to a MAD value of 25 mg/dL
