TET2 and acquired polycythemia vera: In PV patients, the multivariate analysis assessed the neutrophil-to-lymphocyte ratio (NLR) (HR: 4.77, 95% CI: 1.33–17.16; p = 0.017) and a history of remote thrombosis (HR: 1.67, 95% CI: 1.03–1.32; p = 0.014) as independent risk factors for thrombosis; however, no association of TET2 mutation with thrombosis was observed in PV patients (Table 3).
