LEP and breast cancer: The final model suggested that BMI, TG, adiponectin, leptin, visfatin, and resistin were risk factors for BC, and the OR for BMI, TG, adiponectin, leptin, visfatin, and resistin was 0.370 (95% CI: 1.004–4.278, P = 0.049), 6.011 (95% CI: 1.823–15.673, P = 0.004), 0.423 (95% CI: 0.132–0.692, P = 0.005), 0.244 (95% CI: 1.381–3.587, P = 0.001), 1.089 (95% CI, 1.062–1.116; P = 0.001), and 0.513 (95% CI: 3.051–22.790, P = 0.000), respectively (Table 5).
