  • aAll estimates are based on multivariate logistic regression adjusted for race/ethnicity, education, age, and breast cancer knowledge.

  • bThe logistic model for risk comprehension did not include participants' BCRAT risk as a covariate, as the risk comprehension estimate includes BCRAT lifetime risk in its calculation; *, P < 0.05; **, P < 0.01. All estimates are based on participants who have a valid (non-missing) response to each variable.
