Box plots illustrating the distribution of breast density measures to significantly associated SNP genotypes. a) Absolute dense tissue area versus SNP rs3817198 in Caucasian women; b) Absolute volume of dense tissue versus SNP rs3817198 in Caucasian women; c) Absolute volume of dense tissue versus SNP rs3803662 in African-American women; and d) Percent volumetric density (VD%) versus SNP rs4973768 in African-American women. All box plots provide the median (red-line), interquartile range (blue box), 95% confidence interval (black whiskers) and outliers beyond the 95% confidence interval (red plus-signs).
