Figure 2 Comparison of the typical gastroesophageal reflux disease symptom score between the laparoscopic Nissen fundoplication and proton pump inhibitor groups before treatment and at the 2-year follow-up. Range, upper and lower quartiles, and median values are shown. Represents significant P values (^aP < 0.05) for a difference in improvement of symptoms between the LNF and PPI groups. P values are also shown in the right lower corner of each box. LNF: Laparoscopic Nissen fundoplication; PPI: Proton pump inhibitor.
