Fig. 1 Representation of the decision model. M represents a Markov process with 20 total health states [9 alive states, each on or off treatment, and 2 absorbing (death) states]. Cycle length is 3 months. Patients remain in their current health state unless a worse event occurs, with the probabilities of these events contingent upon the treatment option and whether patient is currently on or off treatment. Only one event may occur per cycle. The branch from Well represents the potential events, and other health states have branches with similar structures (not shown). CRNM – clinically relevant non-major, EDO – edoxaban, ECH - extracranial hemorrhage, ICH - intracranial hemorrhage, IS - ischemic stroke, MI - myocardial infarction, SEE - systemic embolic event, S/P - status post, TIA - transient ischemic event.
