Change in mean GERD HRQL. Sham patients were crossed over to active treatment at the 6-month evaluation; thus, the 12-month values in the sham group are symptom scores after the sham subjects received active treatment. ∗Significant difference between active and sham treatment at 6 months (P = 0.003). RF, radiofrequency.
