ACLY and breast cancer: Non-AA patients with SLE had a lower risk of breast cancer if they were positive for anti-dsDNA (SIR 0.24, 95% CI 0.05–0.71), lupus anticoagulant (SIR 0.00, 95% CI 0.00–0.56), or ACL (SIR 0.25, 95% CI 0.05–0.74) (Table 3), and the presence of more autoantibodies was associated with a lower point estimate for breast cancer risk (Table 4).
