For 125 MPN patients, univariate analysis revealed significant associations between thrombosis and age at diagnosis (p < 0.001), age >60 years at diagnosis (p = 0.001), JAK2V617F mutation (p = 0.045), TET2 mutation (p = 0.004), WBC (p = 0.019), NLR (p = 0.002), cardiovascular risk factors (p = 0.039), and history of remote thrombosis (p = 0.001) (Table 2). This evidence concerns the gene TET2 and deep vein thrombosis.
