¹Baseline data compared with 3 mo and end of follow-up data (median of 48 mo);

²Change in percentage compared with baseline, to calculate the change, the absolute values rounded to 2 decimal places instead of 1 were used;

³Frequency multiplied with severity. Scores range from 0 to 24;

⁴Short-Form General Health Survey scores range from 0 to 100, with higher scores indicating better function, except for the bodily pain perception score. GERD: Gastroesophageal reflux disease; NS: Not significant.
