Note.—Unless otherwise indicated, data are odds ratios, and data in parentheses are 95% CIs. FPR is rate per 100 mammograms, and CDR is rate per 1000 mammograms. For breast concern or problem mammography, an interaction with self-reported presence of a lump was evaluated and found to be significant; hence, lump stratum–specific results are presented. Results correspond to Figure E5 (online).
