Results are extracted from Nangalia et al29  because it is one of the rare studies in which all types of MPNs are available. Overall, 143 patients: PV, 43; ET, 57; and PMF, 38. Percentages are expressed for each MPN, irrespective of the MPN drive mutation. Thus, percentages are calculated on a very low number of patients due to the heterogeneity of the disorder, explaining differences with other studies, more particularly for the mutations in splicing genes.
