Among them, transitional (TR) B cell %lymphocyte (odds ratio [OR] = 1.170, 95% confidence interval [CI] = 1.001–1.368), CD25 on IgD− CD24− B cell (OR = 1.151, 95% CI = 1.013–1.307), and HLA DR on CD14− CD16+ monocyte (OR = 1.136, 95% CI = 1.007–1.281) increased risk of rosacea. This evidence concerns the gene CD14 and rosacea.
