  1. “BD awareness”: women reported having heard of breast density, or having been told they had dense breasts. “No BD awareness”: women reported that they had not heard of breast density and had not been told they had dense breasts
  2. “With DBN”: women with BI-RADS 3 or 4 on the baseline mammogram. “No DBN”: women with BI-RADS 1 or 2 on the baseline mammogram
  3. Model 1: Adjusted for outcome-specific covariates specified below and baseline outcome response
  4. Model 2: Model 1 + mutual exposure (density for awareness model, awareness for density model)
  5. Covariates selected based on association with outcome and either exposure:
  6.  Breast cancer worry: Gail 5-year absolute risk score, mammography callback, and history of breast biopsy
  7.  Perceived absolute risk: Gail 5-year absolute risk score, nativity status, health literacy, educational attainment, and history of breast biopsy
  8.  Perceived comparative risk: Gail 5-year absolute risk score, mammography callback, history of breast biopsy, and language of interview
  9.  Uncertainty, risk: Health literacy
  10.  Uncertainty, choices: Nativity status, history of breast biopsy, and health literacy
  11. ¥Cumulative Logistic regression
  12. αLogistic Regression
