* Adjusted for race, gender, median household income of zip code, duration of time on opioids, appointment attendance rate, medical comorbidity score, utilization category, and practice site. Models of individual opioid misuse risk factors adjusted for the other four risk factors
† In unadjusted analyses, using the Cochran Armitage test of trend. In adjusted analyses, using nonlinear mixed effect models and the number of risk factors (none, 1, 2, and 3+) as a continuous variable
