Central memory CD4− CD8− T cell absolute count (OR = 0.952, 95% CI = 0.889–1.019), CCR7 on naive CD4+ T cell (OR = 0.928, 95% CI = 0.866–0.995), CD14+ CD16− monocyte absolute count (OR = 0.915, 95% CI = 0.857–0.977), and CD62L− myeloid dendritic cell (mDC; OR = 0.928, 95% CI = 0.862–0.999) decreased risk of rosacea. Here, CD4 is linked to rosacea.
