Therefore, we conducted a meta-analysis that combined 13 studies from 16 articles including 1,304 BD patients and 1,826 unrelated healthy controls for MICA-A4, MICA-A5.1, and MICA-A9; 14 studies including 1,353 BD patients and 1,876 controls for MICA-A5; and 16 studies involving 1,555 BD patients and 2,086 controls for MICA-A6. Here, MICA is linked to Behcet disease.
