Numbers 1–10 indicate individual patients; A, stomach antrum; B, stomach body; oipA status is expressed as CT repeat number and on/off status. The expression of OipA is regulated by the slipped-strand repair mechanism based on the number of CT dinucleotide repeats in the 5′ signal-sequence coding region the oipA gene (“on” = functional; “off” = nonfunctional)
