Task: Answer Verification
Input (English): Question: Are bone mineral density and bone metabolism related to leptin in hemodialyzed and peritoneally dialyzed uremic patients?
Answer: BMD depends on time of renal replacement therapy. Biochemical markers of bone metabolism poorly correlate with BMD and leptin in dialyzed patients. Leptin is not a predictor of BMD in dialyzed patients.
Output (English): no
