The correlation coefficient of Friedewald’s and the Anandaraja’s LDL-c equations with direct measurement in determining levels of LDL-c from 9 matching studies. The Anandaraja’s LDL-c equation and the direct method of determining LDL-c gave a positive correlation [0.90 (0.85–0.93)] as well as positive correlation between the Friedewald’s equation and the direct method [0.94 (95%0.89–0.96)]. However, there was a stronger positive correlation between the Friedewald’s equation and the direct method compared to the Anandaraja’s equation
