Refusals by race/ethnicity. Potential participants who refused or denied are divided by total number screened. The percentages are displayed by race/ethnicity, and are also separated by reasons for refusal. “No Interest” meant refusal by the woman (diagonal lines), “Poor Follow Up” was an assumption of poor follow-up by either denial to approach by nursing caregiver or similar assessment by researcher (black), “Dislike Blood Draw” reflects a maternal concern about the infant follow-up blood draws (gray), “Moving” connotes moving out of the country (diamonds), “Other Children” indicates the family was too busy with other children for follow-up (white), and “Family No Interest” conveys a refusal by another family member (checks). The overall rate of refusals, based on those screened, was similar across the race/ethnic groups.
