Note: Cell entries are β's from each multivariate ordinary least squares regression model and their 95% confidence intervals (95% CIs). Communication scores range from 0–100; higher scores indicate better communication. Each model controlled for the clustering of patients by primary care provider and the following clinical characteristics: insulin use, A1c, hypertension, history of myocardial infarction, and the number of diabetes complications.
Referent, white.
Referent, English or other primary language.
1 = less than high school degree, 2 = high school degree to some college, 3 = college degree or more.
1 = less than one year, 2 = one to less than two years, 3 = two to less than five years, 4 = five or more years.
Referent, university clinics.
