MEDLINE and EMBASE databases were searched to identify articles in which <jats:italic>PTPN22<\/jats:italic> C1858T polymorphism was reported to be identified in JIA patients and controls. A meta\u2010analysis was conducted to evaluate the association between <jats:italic>PTPN22<\/jats:italic> C1858T polymorphism and RA using allelic contrast. Trial sequential analysis (TSA) was performed. Sixteen separate comparisons involving 5696 JIA patients and 9483 controls (a total of 15,179 subjects) were considered in this meta\u2010analysis. A meta\u2010analysis was performed with all JIA patients as well as JIA patients in each ethnic group. Meta\u2010analysis revealed an association between the T allele of <jats:italic>PTPN22<\/jats:italic> C1858T polymorphism and JIA in all subjects (OR, 1.322; 95% CI, 1.233\u20131.418; <jats:italic>p<\/jats:italic>\u00a0&lt;\u00a0.001). Analysis after stratification by ethnicity indicated that the T allele was significantly associated with JIA in the European population (OR, 1.312; 95% CI, 1.2211\u20131.410; <jats:italic>p<\/jats:italic>\u00a0&lt;\u00a0.001). However, analysis performed in the non\u2010European population showed no significant association between the T allele and JIA. TSA indicated that the observed association between the <jats:italic>PTPN22<\/jats:italic> polymorphism and JIA in all subjects and the European population is consistent with the existing evidence. This meta\u2010analysis confirms that <jats:italic>PTPN22<\/jats:italic> C1858T polymorphism is associated with susceptibility to JIA in Europeans, and that no additional studies are needed to verify these results. However, current evidence in the non\u2010European population is insufficient, and further studies are warranted.<\/jats:p>","DOI":"10.1111\/iji.12590","type":"journal-article","created":{"date-parts":[[2022,7,22]],"date-time":"2022-07-22T13:44:32Z","timestamp":1658497472000},"page":"271-278","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Association between <i>PTPN22<\/i> C1858T polymorphism and juvenile idiopathic arthritis: A meta\u2010analysis update with trial sequential analysis"],"prefix":"10.1111","volume":"49","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4213-1909","authenticated-orcid":false,"given":"Young Ho","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Rheumatology Korea University Anam Hospital Korea University College of Medicine  Seoul Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gwan Gyu","family":"Song","sequence":"additional","affiliation":[{"name":"Department of Rheumatology Korea University Anam Hospital Korea University College of Medicine  Seoul Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,7,22]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.4078\/jrd.2020.27.4.233"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1080\/15513815.2016.1231249"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.3906\/sag\u20101612\u201023"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1038\/ng1323"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.diabres.2006.09.009"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1084\/jem.189.1.111"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1182\/blood.V93.6.2013.406k25_2013_2024"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/0197\u20102456(86)90046\u20102"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.humimm.2013.06.018"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.0006\u2010341X.2000.00455.x"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.315.7109.629"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1186\/1546\u20100096\u201011\u201012"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12969\u2010016\u20100087\u20103"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1126\/science.1092138"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1002\/sim.1186"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1002\/art.21049"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.1186\/1546\u20100096\u201011\u201040"},{"key":"e_1_2_7_19_1","doi-asserted-by":"publisher","DOI":"10.1002\/art.23728"},{"key":"e_1_2_7_20_1","doi-asserted-by":"publisher","DOI":"10.1177\/0961203310381774"},{"key":"e_1_2_7_21_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11033\u2010010\u20100477\u20104"},{"key":"e_1_2_7_22_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00296\u2010007\u20100320\u2010y"},{"key":"e_1_2_7_23_1","doi-asserted-by":"publisher","DOI":"10.4078\/jrd.2022.29.1.46"},{"key":"e_1_2_7_24_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11033\u2010009\u20109637\u20109"},{"issue":"6","key":"e_1_2_7_25_1","first-page":"1146","article-title":"Role of HLA\u2010DRB1 and PTPN22 genes in susceptibility to juvenile idiopathic arthritis in Hungarian patients","volume":"26","author":"Pazar B.","year":"2008","journal-title":"Clinical and Experimental Rheumatology"},{"issue":"10","key":"e_1_2_7_26_1","first-page":"1991","article-title":"Revision of the proposed classification criteria for juvenile idiopathic arthritis: Durban, 1997","volume":"25","author":"Petty R.
