^aEach regression model also included facility type (clinic vs hospital), facility branch (Army vs other) and 6 regions and patients were clustered by MTF
^bAnnual measure computed as FTE per 100,000 patients at the MTF
^cFor facilities with no utilization the number of visits per user was imputed as zero
