To evaluate the variance of general serum protein expression between MetS and non-MetS subjects, we calculated the difference of serum total protein (TP, sum of albumin and globulin) levels between MetS and non-MetS subjects as the control, and found it was similar (7.3 ± 0.4 vs. 7.2 ± 0.4 g/dl, P = 0.357, Table 1). This evidence concerns the gene ALB and metabolic syndrome.
