BD exhibited a negative correlation with CD64 on CD14+ CD16+ monocyte (OR = 0.812, 95% CI: 0.713-0.925, P = 0.001), CD64 on monocyte (OR=0.834, 95% CI: 0.735-0.947, P = 0.005), CX3CR1 on CD14- CD16- (OR = 0.838, 95% CI: 0.740-0.950, P = 0.006), and CD64 on CD14+ CD16- monocyte (OR = 0.837, 95% CI: 0.738-0.950, P = 0.006). This evidence concerns the gene FCGR1A and Behcet disease.
