Model Diagram. *Patients in the off-treatment health state can experience the same events as patients in the on-treatment health states but at different risk levels. This diagram presents all potential health states that a patient may occupy while in the model. Arrows indicate potential health state transitions of patients. Dark Grey health states denote the treatment or originating health states. Patients are exposed to risks of recurrent VTE, CRNM bleed, CTEPH, major bleed, and death. The light grey health states (Recurrent VTE and CRNM bleed) are transient health states; that is, patients spend a temporary amount of time in this health state, and then return to their originating health state. CTEPH and Major bleeds are semi-absorbing health states; where patients do not experience any further events and remain in this health state until death. Major bleed is semi-absorbing if it is an IC bleed. If it is a non-IC bleed, it is a transient health state. PTS is modelled in the background and it is not a separate health state, but patients accrue expected costs and quality of life utility decrements associated with PTS while alive
