MME, oral morphine milligram equivalent. Predicted population rates using average marginal effects. The models utilized complete case regression. For the regressions including the full cohort and the top 6 frequent conditions, the interaction term between race/ethnicity and LEP status was included because the likelihood ratio test was significant comparing the models with and without the interaction term. For the regression of top 3 pain conditions, the interaction between race/ethnicity and LEP was not included because the likelihood ratio test was nonsignificant.
