Figure 3.

Age-adjusted means and 95% confidence intervals for MRI absolute dense volume and Cumulus absolute dense volume by BRCA1/BRCA2 genetic status. P-values are for the comparisons with the group of women with uninformative BRCA1/2 genetic test results, as assessed by linear regression (P-values further adjusted for BMI and parity are given in parentheses). Arithmetic means are presented for the Cumulus measurement; geometric means are shown for the MRI measure (for which the regression analyses were based on log-transformed values). Box areas are proportional to sample size.
