Correlation between circulating interleukin-18 level and systemic lupus erythematosus: a meta-analysis

Abstract This study is a meta-analysis aimed at pooling reported data and clarifying the association between circulating level of interleukin-18 and systemic lupus erythematosus (SLE). We searched medical databases including Medline/Pubmed, Embase, Scopus, The Cochrane Library, and Web of Science th...
