Fig. 9From: Assessment of estimated low-density lipoprotein-cholesterol (LDL-c) equations: a systematic review and meta-analysisThe correlation coefficients of Friedewald’s and the Hattori LDL-c equations with direct measurement in determining levels of LDL-c from 4 matching studies. Both the Friedewald’s and the Hattori LDL-c equations demonstrated a positive correlation with the direct method of measuring LDL-c. There was no statistical difference in their correlation coefficientsBack to article page
