CRP and metabolic syndrome: Many recent studies evaluated the genetic association between CRP single-nucleotide polymorphisms (SNPs) and MetS in different populations.2, 9, 10, 11, 12, 13, 14, 15, 16Some studies showed the association of CRP polymorphisms,10, 12, 14whereas some other studies did not.11, 13Therefore, a comprehensive systematic review and meta-analysis are essential to evaluate the relationships between CRP polymorphisms and MetS.
