↵a Quality measures assessed in 2005 and 2007 (optimal diabetes care and optimal CAD care), 2006 and 2009 (composite preventive services), and 2005 and 2009 (generic drug use).
↵b Unadjusted mean values.
↵c Estimated using a model that adjusted for the following year-specific, patient-level variables: sex, Medicaid status, age, number of primary care visits per year, and number of medications prescribed.
↵d For the difference between slopes.
