In the subgroup with a follow-up date of more than four years, patients with hypothyroidism can reduce the risk of breast cancer, with borderline significance (OR 0.96, 95% CI 0.91–1.00, P < 0.001).
In the subgroup with a follow-up date of more than four years, patients with hypothyroidism can reduce the risk of breast cancer, with borderline significance (OR 0.96, 95% CI 0.91–1.00, P < 0.001).
The results revealed that the hypothyroidism could reduce the risk of breast cancer was borderline significant (OR:0.96 95%CI:0.92–1.00, P < 0.001), and there was no heterogeneity(I 2 = 0, P = 0.577).
