Association between Gastric Cancer Risk and Serum Helicobacter pylori Antibody Titers

Table 1

	“Negative high” group; (HpAb 3.0–9.9 U/mL)	“Over 10 U/mL” group; (HpAb ≧ 10 U/mL)	value
Mean age	72 ± 9.7	70 ± 9.7	n.s.
Sex (male ratio)	36.0% (150)	36.0% (320)	n.s.
Gastric cancer	0.5% (2)	0.9% (8)	n.s.

p values were calculated by chi-square test. GC was detected in 8 patients in the “over-10 U/mL” group, but also in 2 patients in the “negative-high” group.
