*Du = Duodenal ulcer; GC = gastric cancer; GE = gastric erosion; GU = gastric ulcer; GUDU = gastric and duodenal ulcers; NUD = non-ulcerative diseases.

^§Incomplete vacA = either vacA s or vacA m regions were not detected (4/10 vacAs1 was detected & vacAm was missing, 2/10 vacAs2 detected and vacAm missing, 2/10 vacAm1 detected and vacAs missing and for 2/10 both vacAs and vacAm were missing).
