* Numbers are proportions of respondents indicating that they would prescribe medications for each or any of the three diabetes-related risk factors; Numbers of physicians per practice variables are indicated in the table. Due to the factorial experimental design, numbers within each patient and physician variable category are equal.
† Socioeconomic status (SES) depicted by occupation of lawyer versus janitor.
‡ Physician experience groups divided as ≤12 years vs ≥22 years of clinical experience.
§ Practice sizes defined by number of physicians (1, ≤10, or >10).
