^a Adjusted for age, education, first degree relative with breast cancer, benign breast disease, general health, breast cancer risk, and health anxiety; ^b Odds ratios in bold are significant with p < 0.05; ^c Age per 1 year increase; ^d FDR = first degree relative; ^e General health per one point increase; ^f Health anxiety per one point increase; ^g n = 11 people with a physician health locus of control were excluded due to small sample size
