Table 1 Breast area, dense area and percent density in the four quadrants and the whole breast (mean ± standard deviation from 110 cases)

From: Evaluation of the association between quantitative mammographic density and breast cancer occurred in different quadrants

  1. All pair-wise comparisons are significant with p < 0.05 except:
  2. aThe breast area in UO and UI are not significantly different
  3. bThe percent density in UO and LI are not significantly different
