Comparison of Friedewald and Sampson equations for calculation of LDL-cholesterol

Key Points

• To compare the Friedewald and Sampson equations in terms of LDL-cholesterol calculation and invalid results.
• Evaluated the effectiveness of Friedewald and Sampson equations in clinical settings.
• Assessed the percentage of invalid results linked to each equation.
• Analyzed agreement between the two equations when triglycerides were ≤4.5 mmol/L.
• Identified significant differences in invalid results between the two equations.
• Demonstrated good agreement in LDL-cholesterol results when triglycerides were ≤4.5 mmol/L.
