This investigation focused on the effect of iAs exposure on MetS and whether the results are consistent in different subgroups.Patients and Methods: The present study was conducted on 629 men and 616 women aged 35– 70 years and living in Xinjiang Uygur Autonomous Region, China. The 1:1 propensity score matching (PSM) was adopted to regulate the confounding factors, and the multivariate logistic ...
