Incidence rate of map-like redness during the long-term observation period. The frequency of map-like redness in all patients increased significantly over time from the first EGD up to 15 years subsequently. The frequency of map-like redness 20 years after eradication was significantly decreased compared with that 15 years after eradication. *: p < 0.05 versus first EGD, †: versus 5 years subsequently, ‡: versus 10 years subsequently, and §: versus 15 years subsequently
