Fig. 1: Transition probabilities to death in ET.

Comparison of the direct (i.e., from ET diagnosis, black line) and indirect (i.e., via thrombosis [red line], evolution to MF [blue line] or BP [green line]) transition probabilities to death (absorbing state) over time in 891 ET patients. Transition probabilities are defined as the probability of going from a given state to death in a Markov process within a multistate model approach.
