Relationship between the IL-10 (-1082 A/G) polymorphism and the risk of immune/idiopathic thrombocytopenic purpura: A meta-analysis.

•This meta-analysis aimed to determine whether the IL-10 (−1082) polymorphism is associated with an increased risk of immune thrombocytopenic purpura.•This meta-analysis included six eligible studies with 384 cases and 409 controls.•There is scarce evidence to confirm an association between the IL-10 (−1082) polymorphism and the risk of immune thrombocytopenic purpura.•The IL-10 (−1082) polymorphism might be associated with the risk of acute ITP.
