ALB and metabolic syndrome: However, the association between ALB, number of pregnancies, and live births and MetS was a linear relationship, and the risk of MetS increased with increasing ALB, number of pregnancies and live births (ALB, P for nonlinearity = 0.186, Fig. 1B; the number of pregnancies, P for nonlinearity = 0.803, Fig. 2A; the number of live births, P for nonlinearity = 0.251, Fig. 2B).
