From: An improved method for estimating low LDL-C based on the enhanced Sampson-NIH equation
Development of the eS LDL-C equation. With LDL-C as measured by BQ reference method (BQ-LDL-C) as the independent variable, the eS LDL-C equation was established by least-square regression analysis on a training dataset (N = 12,196). The solid black line is the linear fit for the regression equation. Regression equation and its coefficients are shown in figure. Results are color coded by TG level with the values indicated in the legend
