I remember seeing a similar study that took place at a busy walk in clinic in an area with a very diverse population. People would come in and get treated by whichever of the doctors on duty that day was available.
The researchers found that when successful treatment would require the patient to follow the doctors instructions after leaving, such as getting a prescription filled, taken the full course of medication, doing or refraining from certain exercises, etc., the patient was more likely to actually do those things the more the doctor was like them in things like race, gender, and ethnicity.
