Gastric cancer	HCV-treated	HCV-untreated	HCV-uninfected	p value
Number	7545	30,180	30,180
Mean years’ follow up ± SD	2.901 ± 1.804	3.167 ± 1.864	3.124 ± 1.843
Event number, n (%)	1 (0.01)	15 (0.05)	2 (0.01)
Competing mortality, n (%)	127 (1.68)	1837 (6.09)	636 (2.11)
Cumulative incidence, % (95% CI)	0.177 (0.018–0.953)	0.16 (0.073–0.325)	0.007 (0.001–0.024)	0.0056
