Univariate analysis for arterial thrombosis-free survival (A-TFS) identified older age (p < 0.001), male sex (p = 0.03), presence of JAK2 mutation (p = 0.04), cardiovascular risk factor (p = 0.002) and previous arterial event (p = 0.006) as risk factors for arterial thrombosis during follow-up. Here, JAK2 is linked to Arterial thrombosis.
