↵5-151 95% Confidence intervals for multivarite adjusted odds ratios.
↵5-152 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.
