Logistic regression analysis examining the relationship between the presence of GER symptoms in H. pylori-infected subjects (no/yes=0/1) as the dependent variable and other independent variables. The coefficients obtained from the logistic regression analysis were also expressed in term of the odds of occurrence of an event.
