Therefore, we performed this meta-analysis to better assess the relationship between CTLA-4 gene polymorphisms and DM in a larger pooled population.<\/jats:p>\n               <jats:p>Methods: PubMed, Embase, Web of Science, and CNKI were systematically searched for eligible studies. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to estimate the strength of associations between CTLA-4 gene polymorphisms and DM in all possible genetic models.<\/jats:p>\n               <jats:p>Results: A total of 76 studies were finally included in our analyses. Significant associations with susceptibility to type 1 diabetes mellitus (T1DM) were detected for rs231775 (dominant model: P=0.008, OR = 0.83, 95%CI 0.73\u20130.95; recessive model: P=0.003, OR = 1.27, 95%CI 1.09\u20131.50; allele model: P=0.004, OR = 0.85, 95%CI 0.77\u20130.95) and rs5742909 (recessive model: P=0.02, OR = 1.50, 95%CI 1.05\u20132.13) polymorphisms in overall population. Further subgroup analyses revealed that rs231775 polymorphism was significantly associated with susceptibility to T1DM in Caucasians and South Asians, and rs5742909 polymorphism was significantly associated with susceptibility to T1DM in South Asians. Moreover, rs231775 polymorphism was also found to be significantly associated with susceptibility to type 2 diabetes mellitus (T2DM) in East Asians and South Asians.<\/jats:p>\n               <jats:p>Conclusions: Our findings indicated that rs231775 and rs5742909 polymorphisms may serve as genetic biomarkers of T1DM, and rs231775 polymorphism may also serve as a genetic biomarker of T2DM.<\/jats:p>","DOI":"10.1042\/bsr20190309","type":"journal-article","created":{"date-parts":[[2019,4,15]],"date-time":"2019-04-15T16:35:13Z","timestamp":1555346113000},"update-policy":"https:\/\/doi.org\/10.1042\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Associations between cytotoxic T-lymphocyte-associated antigen 4 gene polymorphisms and diabetes mellitus: a meta-analysis of 76 case\u2013control studies"],"prefix":"10.1042","volume":"39","author":[{"given":"Min","family":"Chen","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, Ningbo No. 6 Hospital, Ningbo 315040, Zhejiang, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1858-4927","authenticated-orcid":false,"given":"ShuMin","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Ningbo No. 6 Hospital, Ningbo 315040, Zhejiang, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"288","published-online":{"date-parts":[[2019,5,15]]},"reference":[{"key":"2021111619344680600_B1","first-page":"1015","article-title":"Mitigating micro-and macro-vascular complications of diabetes beginning in adolescence","volume":"5","author":"Moore","year":"2009","journal-title":"Vasc.
