The correlation coefficients of Friedewald’s and the Puavilai’s LDL-c equations with direct measurement in determining levels of LDL-c from 6 matching studies. Both equations demonstrated a positive correlation with the direct method of measuring LDL-c. However, the Puavilai’s equation established a stronger correlation with the direct method [0.95 (95% CI 0.91–0.97)] than Friedewald’s LDL-c equation [0.93 (95% CI 0.89–0.95)]
