  1. Note: Control variables used for adjustment: patient age, sex, and insurance status. Bold denotes statistically significant (p < 0.05) differences between the intervention and control group. Statistically significant differences are denoted in the following manner: * p < 0.05, ** p < 0.01, ***p < 0.001
