Figure 4 Logistic regression curves of age and duodenal ulcer disease as independent factors to explain Helicobacter pylori incidence. The model had a highly significant fit (age OR = 0.9827, P < 0.0001; DU OR = 3.6077, P < 0.0001). A posterior test for the age/DU interaction had a nonsignificant result (β3 = 0.0085, SE = 0.0168, P = 0.6142, OR = 1.0085, CI- = 0.9758, CI+ = 1.0423). DU: Duodenal ulcer; OR: Odds ratios; CI: Confidence intervals; H. pylori: Helicobacter pylori.
