Task: Answer Verification
Input (English): Question: Do plasma plant sterol levels reflect cholesterol absorption in children with Smith-Lemli-Opitz syndrome?
Answer: Although the ratios of plant sterols to cholesterol in plasma has been used as a surrogate for cholesterol absorption in adults and children, these ratios may not accurately reflect cholesterol absorption in children with SLOS. These ratios should not be used as a surrogate for cholesterol absorption in children without further validation.
Output (English): no
