CPB1 and ductal breast carcinoma in situ: CPB1 expression in tumoral lesions of all women (N = 82) was associated with DCIS before (odds ratio (OR) = 1.02; 95% confidence interval (CI) = 1.01–1.03; p-value < 0.001, Table 2) and after adjustment for age at mastectomy (OR = 1.02; 95% CI = 1.01–1.03; p-value < 0.001), and for age at mastectomy and BMI (OR = 1.02; 95% CI = 1.01–1.04; p-value < 0.001).
