Table 2 Pearson correlation coefficients for tests of correlation between mammographic measures and between mammographic measures and age

From: The combined effect of mammographic texture and density on breast cancer risk: a cohort study

  Age DV PDV Texture
Age 1 −0.16 −0.29 − 0.35
DV   1 0.27 0.20
PDV    1 0.90
Texture     1
  1. Age, breast density, and texture were assessed at the first digital screening mammogram
  2. DV dense volume (natural logarithm (Ln) transformed), PDV percent dense volume (Ln transformed)
  3. The p values were statistically significant (<0.01) for all correlation coefficients
