↵aAdjusted for mammography registry site, age at baseline screening mammogram ages 35 to 39, rural/urban status at baseline, and whether additional screening occurred before age 40.
↵bDefined as not having a mammogram, compared with having 1, captured in the BCSC data between ages 40 and 45, including screening, diagnostic, or unknown mammograms.
↵cDefined as the first future screening mammogram between ages 40 and 45 among women who returned to a BCSC facility for mammography; ages 43 to 45 compared with 40 to 42.
