After FDR adjustment, we detected protective effects of 3 immuno-phenotypes on T1D: CCR2 on plasmacytoid dendritic cell (OR = 0.873, 95% CI: 0.818–0.933, PFDR = 0.007), CCR2 on CD62L + plasmacytoid dendritic cell (OR = 0.873, 95% CI: 0.818–0.933, PFDR = 0.007), FSC-A on Natural Killer T (OR = 0.705, 95% CI: 0.597–0.834, PFDR = 0.007) (Table S13, Supplemental Digital Content, http://links.lww.com/MD/N650). Here, CCR2 is linked to type 1 diabetes mellitus.
