Fig. 1 Frequency distribution of patients with (■) or without (□) peptic ulcers with respect to the combined cagA/iceA genotypes. Bars represent percentages of the total number of patients with (n = 44) and without (n = 28) ulcers with a single genotype (n = 72). Cases containing multiple vacA (n = 10) and/or iceA (n = 14) genotypes, as well as untypeable strains for vacA (n = 1) or iceA (n = 2), were excluded from analysis. Probabilities for ulcer disease, as calculated from model 2 (see Table 6), are shown in parentheses below each of the four combinations of cagA/iceA genotypes as indicated on the horizontal axis.
