Last Updated: 2019-10-25

Results Overview

Take-up of preventative services was scored as either zero (did not utilize any post-consultation services) or 1 (utilized at least 1 post-consultation service). Four non-incentivized post-consultation preventive services were offered (for BMI, blood pressure, cholesterol, and/or diabetes); the subject had the opportunity to select service(s) after meeting with their assigned doctor.

Participant Flow

We recruited 1374 black men in barbershops and flea markets to take the baseline survey. The subjects were given a coupon which allowed them entrance to the clinic.

1374 participants were recruited and completed the baseline survey prior to coming to the clinic. 667 filled out the baseline survey but did not come to the clinic and were not randomized. 70 additional participants were excluded from participation and were not randomized.
