Multivariate logistic regression was used to assess the association of each depression symptom, MDE, and MDD (as the outcome variable) with the following independent variables or factors entered into the initial model in each regression: age, gender, cannabis dependence, alcohol dependence, heavy substance use, early substance use, and early conduct disorder. Final logistic models were determined using the Backward Stepwise approach of Wald.
Factors in this column are those independent variables from the initial model which appeared in the final logistic regression model in each analysis. Alpha was set at 0.05, and p-values < 0.05 were considered significant.
