  • 3-150 Significant in women in multivariate analyses.

  • 3-151 IgG antibody status was used as the dependent variable. Other pain episodes were not associated with H pylori infection.

  • 3-152 The upper odds ratio represents the risk of having the symptom in IgG borderline cases compared with IgG seronegative people. The lower odds ratio is the corresponding risk in IgG seropositive people compared with IgG seronegative people.

  • 3-153 Confidence intervals for multivariate adjusted odds ratios.

  • 3-154 Significant in men in multivariate analyses.
