MMP9 and Arterial thrombosis: Specifically, the MMP-9 rs3918242 CT genotype (compared to CC) was significantly associated with an increased risk of arterial thrombosis (OR = 4.206, CI 1.337–13.234, p = 0.014) and overall thrombotic events (both arterial and venous thromboses combined) (OR = 3.200, CI 1.110–9.258, p = 0.031).
