  1. In the Diabetes Prevention Program (DPP) 13 phone solicitations (a method that was not used in the POP-ABC study) yielded 0.9% of Caucasian and 1.3% of African American recruitment. The Internet was not a recruitment source for the DPP. The DPP columns do not add up to 100% because of missing values and “other” category. The POP-ABC category of Flyer/Brochure is equivalent to the DPP category of Poster/Newsletter13. POP-ABC = Pathobiology of Prediabetes in A Biracial Cohort.
