  1. BBD benign breast disease, BI-RADS Breast Imaging Reporting and Data System (I = almost entirely fat; II = scattered fibroglandular densities; III = heterogeneously dense; IV = extremely dense), HR hazard ratio, MBD mammographic breast density, OR odds ratio, RR relative risk, SIR standardised incidence ratio, WPP Wolfe’s parenchymal pattern (N1 = non-dense; P1 = ductal prominence occupying 25% of the breast; DY = extremely dense).
  2. avs no BBD and fatty/scattered densities.
