The correlation coefficients of the Friedewald’s and the de Cordova’s LDL-c equations with the direct measurement in determining levels of LDL-c pooled from 6 matching studies. The de Cordova’s LDL-c equations and the Friedewald’s equation both demonstrated a positive correlation with the direct method of measuring LDL-c [0.87 (95% CI 0.76–0.93) and 0.94 (95% CI 0.88–0.97), respectively]. However, the Friedewald’s equation established a stronger positive correlation with the direct method of determining LDL-c compared with the de Cordova’s LDL-c equation
