Figure 2 Logistic regression curves of age and sex as independent factors to explain gastric ulcer disease incidence. The model has a significant fit, with contributions of both coefficients (χ2 = 30.5, P < 0.0001). Additional test for the age/sex interaction had a nonsignificant result (β3 = -0.011, SE = 0.0161, P = 0.4844, OR = 0.989, CI- = 0.958, CI+ = 1.021). OR: Odds ratios; CI: Confidence intervals; GU: Gastric ulcer.
