  1. [1] The regression was performed as generalized linear mixed regression model for count outcomes, assuming a Poisson distribution for the outcome variable using a log-link. The regression results presented here are the exponentiated values of the specified coefficients to be directly interpretable as the percent change in utilization relative to enrollment in COPE
