a
Recent defined as having within past two years.
b
Screening responses include part of a routine exam, my healthcare provider told me I was high-risk, I have a family history of breast cancer, and I requested it.
c
Diagnostic responses include follow-up of an abnormal mammogram and because of a breast problem.
d
P-value based on Rao-Scott Pearson chi-square test for all variables except income status. Income status p-value based on Wald F test from unadjusted logistic regression model (due to multiply-imputed data).
