Flow chart Of 6,508 total households contacted, 2,146 were eligible and initially consented, 708 were ineligible, and 3,654 were outright refusals. Of those who were eligible and initially consented, 1,385 completed the survey and 761 were later refusals. Of the outright refusals, 906 were estimated ineligible (the quotient of 708 ineligible divided by the sum of 2,146 eligible and initially consented plus 708 ineligible, multiplied by 3,654 outright refusals), and 2,748 were estimated as eligible.

Response rate calculation (using Council of American Survey Research Organizations formula) for Arkansas Cardiovascular Health Examination Survey sample. The response rate was the number who completed surveys (1,385) divided by the sum of the number who were eligible and initially consented (2,146) plus the estimated number who were eligible among those who refused (2,748): 1,385/(2,146 + 2,748) = 28.3%.
