Table 4 summarizes other significant factors for breast cancer including a vegetarian diet (OR 0.42, 95% CI: 0.27–0.65, P < 0.001), BMI > 23 kg/m2 (OR 2.00, 95% CI: 1.28–3.13, P = 0.003), primiparity >30 years (OR 2.38, 95% CI: 1.43–4.00, P = 0.001), serum albumin > 4 g/dl (OR 0.30, 95% CI: 0.19–0.47, P < 0.001), and daily soy isoflavone intake > 22 mg (OR 0.37, 95% CI: 0.24–0.60, P < 0.001). Here, ALB is linked to breast cancer.
