Table 2.

Multivariate binary logistic regression of factors predictive of an existence of migraine headache while accounting for confounders. All variables were binarized, and odds ratios (OR) were calculated for the second option compared to the first option labeled as “[reference]”. For instance, compared to patients <39 years of age (reference), patients ≥39 years old were 1.16 times (95% CI 1.05-1.28) more likely to experience migraine headache
