Table 1

Baseline characteristics of treated patients (n = 56)a.

Mean age (yr)
Male sex, (%) 36 (64.2)
Mean heartburn score
Mean HRQL scoreb  
Mean SF-36 mental
Mean SF-36 physicalc 41 ± 7
Daily PPI use, (%) 56 (100)
Median 24-h pHd 15.85 (5.9–18.2)
Median LES pressure (mmHg) 8.44 (7.2–11.7)
<2 cm hiatal hernia, (%) 28 (50)
Erosive esophagitis at EGD, (%)e 14 (25)

EGD: esophagogastroduodenoscopy; LES: lower esophageal sphincter.
aMeans report ±1 SD, medians report 25th and 75th percentile ranges, and proportions report absolute numbers (percentiles).
bHeartburn and heartburn-related quality of life scores (higher scores for worse symptoms).
cSF-36 physical score (higher scores for better function; U.S. general ‘‘healthy group’’ population mean = 55.3).
dPercentage of time esophageal pH was <4 (off antisecretory medications).
eTen patients with grade A and four patients with grade B esophagitis according to the Los Angeles classification.
