  1. 1 For a reference value of 30%
  2. 2 P-value for linear trend in mammographic values across categories of a given SES variable
  3. 3 For a reference value of 35 cm2
  4. 4 For a reference value of 90 cm2
  5. 5 Adjusted for age at mammography and mammographic view
  6. 6 Additionally adjusted for BMI
  7. 7 Further adjusted for height, smoking status, age at first full-term pregnancy and number of full-term pregnancies (see Statistical Methods)
  8. 8 Q1 to Q5 refer to the England and Wales general population fifths of Townsend score at LSOA level
