Accuracy of low-density lipoprotein cholesterol estimation equations according to drinking status: A cross-sectional study

High low-density lipoprotein cholesterol (LDL-C) and triglyceride (TG) levels are associated with heavy alcohol consumption, but the accuracy of LDL-C estimation equations according to drinking status remains unclear. We analyzed direct LDL-C and drinking-status data from 28,882 participants in the Korea National Health and Nutrition Examination Survey, classified as non/ex-drinkers, moderate drinkers, or binge drinkers. Mean absolute deviation (MAD) was calculated for the Friedewald, Martin-Hopkins, and Sampson equations relative to directly measured LDL-C, and 95% confidence intervals for th
