Predictors of Referral Completion: Logistic Regression Analysis

Predictors of Referral CompletionAdjusted Odds Ratio95% Confidence Interval
Note: Predictor variables were retained in the final model only if they significantly improved model fit (P <.05 for the likelihood ratio test). Logistic regression with the generalized estimating equation was used to estimate odds ratios and their 95% confidence intervals.
