In ET patients, the multivariate analysis showed that TET2 mutation and a history of remote thrombosis were independent risk factors for thrombosis in ET patients, with an HR of 4.1 (95% CI: 1.40–12.01; p = 0.01) for TET2 mutation and 6.89 (95% CI: 1.45–32.68; p = 0.015) for history of remote thrombosis (Table 3). This evidence concerns the gene TET2 and essential thrombocythemia.
