Task: Answer Verification
Input (English): Question: Do serum osmolarity and haematocrit modify the association between the impedance index ( Ht ( 2 ) /Z ) and total body water in the very old : the Newcastle 85+ study?
Answer: The association between the impedance index and TBW was not modified by hydration status, which may support the utilisation of leg-to-leg bioimpedance for the assessment of body composition in the very old.
Output (English): no
