Input: Consider Input: Question: Does biofeedback-guided control of abdominothoracic muscular activity reduce regurgitation episodes in patients with rumination?

Input: Consider Input: Question: Is polymorphism of methylenetetrahydrofolate reductase gene ( C677T MTHFR ) a confounding factor of the relationship between serum uric acid level and the prevalence of hypertension in Japanese men?
Answer: The mutation of C677T MTHFR was not independently associated with the prevalence of hypertension or BP levels although serum UA was. Furthermore, the relationship between serum UA and BP was not modulated by the MTHFR mutation in Japanese men.


Output: no
