IGFBP7 and breast cancer: In the univariable survival analyses of IGFBP7 expression in biopsied breast cancer tissue in the SCAN-B cohort, IGFBP7 expression, Q4 compared to Q1, was not associated with increased risk of recurrence (HR 0.96 [95% CI 0.76–1.22]) or distant metastasis (HR 1.00 [95% CI 0.77–1.32], Supplementary Table 4).
