From: An equation for calculating small dense low-density lipoprotein cholesterol
Linear regression between estimated and measured small-dense low-density lipoprotein (sd-LDL) cholesterol levels in the validation set. Linear regression formulas using modified equation (A) and original equation (B). Solid line is the linear fitting for the indicated equation. Dotted line is the line of identity. Listed coefficient of determination (R [2]) and mean absolute deviation (MAD) are from the validation set, and the number in parentheses are from training set. Residual errors are plotted for measured sd-LDL (msd-LDL) cholesterol, LDL cholesterol, and triglycerides (TG) for modified equation (C, E, G) and original equation (D, F, H). Points are colored according to the TG intervals. Data of 12,718 participants in the validation set from Beijing Health Management Cohort were analyzed
