Median values for TF (A) and Tn (B). H = usual hyperplasia; AH = atypical hyperplasia; DCIS: ductal carcinoma in situ; invasive: invasive breast cancer. Numbers in parentheses indicate the sample sizes for each group. Y axis units are Abs/μL. TF expression was higher in women with AH compared to H (p = .043), and trended higher in women with DCIS compared to normals (p = .07) and women with H (p = .09).
