From: An improved method for estimating low LDL-C based on the enhanced Sampson-NIH equation
Effect of validating low estimated LDL-C results with the eS LDL-C equation. LDL-C was calculated by the standard equations from the validation data set that contained apoB test results. Those test results and are below the 70 mg/dL cutpoint for LDL-C are shown and classified as either being false lows or true lows by comparison against BQ LDL-C (red bars). False low and true low test results are also shown after repeat estimation by the eS LDL-C equation (red bars with black diagonal stripes). Results are shown for F LDL-C (A, TG ≥ 400 mg/dL, N = 3894), F LDL-C (B, TG ≥ 800 mg/dL, N = 4115), eM LDL-C (C, TG ≥ 800 mg/dL, N = 4115), and S LDL-C (D, TG ≥ 800 mg/dL, N = 4115) equations. Results are graphed as the percentage of the entire population with absolute numbers in each category shown over the bars
