a
Model 1 adjusted for baseline screening status, lay health worker agency, language proficiency, years in the U.S., education, employment, marital status, insurance, family history of breast cancer, and household clusters
b
Model 2 adjusted for all covariates in Model 1, plus changes in knowledge and media exposure scores
CBE, clinical breast examination; LHWO, lay health worker outreach; ME, media education
