  1. aGeneral estimating equations were used to calculate performance measures, correcting for multiple screening rounds within the same patient. All measurements are per 1000 examinations
  2. MRI magnetic resonance imaging, N/A no cancers, recalls, or biopsies were found in this category and no 95% CI of this measure could be calculated, 95% CI Wald 95% confidence intervals
