Serum Cu levels ≥99.48 μg/dL are significantly linked to diabetes risk, while serum Se levels ≥122.74 μg/L are associated with diabetes risk and levels <157.56 μg/L with elevated heart attack risk. Serum metal mixtures containing Cu, Se and Zn were significantly and positively associated with risk of diabetes, hypertension and heart attack.
