*CI denotes confidence interval; MSA, metropolitan statistical area; OR, odds ratio. ORs and 95% CIs are for osteopathic physicians (DOs) relative to allopathic physicians (MDs).
†The results were computed using logistic regression. The adjusted ORs were based on a multiple logistic regression model that included each of the characteristics in the table.
