^*Autonomy in logistic-based decisions measured by: “I have adequate time to spend with my patients during typical office/patient visits.”

Autonomy in knowledge-based decisions measured by: “I have the freedom to make clinical decisions that meet my patients’ needs.”

^**Urbanicity is a categorical variable, and thus standard deviations were not calculated.
