Note. N = 242 (with the exception of “Individual/Group”, “Medication”, and “Medical Provider Visit” where N = 241). Only observations with values for each variable in the model were included. OR = Odds Ratio; 95% CI represents 95% Wald Confidence Limits; Multivariate chi-square is Likelihood Ratio.

Predictor variables may be on different scales (see Method section); thus, the interpretation of odds may have different interpretations based on the predictor of interest.
