From: An improved method for estimating low LDL-C based on the enhanced Sampson-NIH equation
Comparison of estimated LDL-C versus BQ-LDL-C. LDL-C was calculated in patients (validation set, N = 12,210) with a wide range of LDL-C values by eS-LDL-C (A), F-LDL-C (B), eM-LDL-C (C), and S-LDL-C (D) equations and plotted against LDL-C as measured by BQ reference method (BQ-LDL-C). Solid lines are the linear fit for indicated regression equations. Results are color coded by TG level with the values indicated in the legend (mg/dL). Grey triangles are patients with Type III hyperlipidemia
