HYPERTENSION
Participants were recruited between October 2017 and December 2020 from 2 large, Midwestern health care systems. Potential participants were identified using the electronic health record linked with the Wisconsin Collaborative for Health Quality (WCHQ) hypertension registry.Potential participants were mailed an introductory packet summarizing the study with a prepaid opt-out postcard. Individuals who did not opt-out were contacted for telephone screening. If inclusion criteria were met, the individual was invited for an in-person visit (visit 1) for eligibility assessment. Written informed consent was obtained at the start of visit 1. Data on self-reported race (Black, White, or other [Asian, American Indian or Alaska Native, Native Hawaiian or other Pacific Islander, unknown, or not reported]) and ethnicity (Hispanic or non-Hispanic) were collected to describe the population characteristics and to ensure we had a representative and diverse population. BPs were measured with an automated sphygmomanometer (Dinamap; GE)
