Age (years)	60.50 ± 4.90	60.13 ± 3.91	62.63 ± 3.66	0.451^a
Sex (male/female)	3/5	4/4	3/5	0.842^c
Body mass index	23.35 ± 0.85	23.82 ± 0.88	22.79 ± 0.81	0.697^a
Smoker (+/−)	2/6	1/7	2/6	0.777^c
Disease duration (years)	—	5.63 ± 0.88	10.50 ± 1.54	0.014^b
Medications (+/−)
Antibiotics	—	3/5	2/6	0.590^c
Antacids	—	1/7	2/6	0.522^c

Data are presented as number (mean ± standard deviation). There was no significant difference in sex, age, BMI, and smoking between the three groups. There was no significant difference in medications between NAG and CAG groups. There was a significant difference in disease duration between NAG and CAG groups (), ^ap value by variance analysis test. ^bp value by independent samples t-test. ^cp by χ² test.
