Note. CI = confidence interval; male = first-degree male relative (father, brother, or son); OR = odds ratio. Selected results reported.

^aCovariates included in the model were age, income, race/ethnicity, education, nativity, and geographic region.

^bValues represent differences in mean number of mammograms (first group mean—second group mean) and analysis includes the following covariates: age, income, race/ethnicity, education, nativity, geographic region, insurance status, physician recommendation, no care because of cost, delayed care because of cost, and system barriers.
