Median hematocrit value decreased from 54% at diagnosis to 45% at 12 months, and adequate hematocrit control over time ( 60 years, and microvascular symptoms constituted the main indications for starting cytoreduction. Median duration without initiating cytoreduction was significantly longer in patients younger than 50 years ( %K Low-risk %K Myelofibrosis %K Phlebotomies %K Polycythemia vera %K Thrombosis %~
