Figure 2.

Construction of the delayed intervention effect on clinical state, sC, via zoomed in view of Figure 1. Each transition (arrow) in Figure 1 encodes 2 transitions with different probabilities (the dashed and dotted arrows in this figure), each of which depend on the engagement state of the user 3 months ago, that is, the last entry of the memory state M. Specifically, the probability of transitioning to a better clinical state will be larger if the user was in the engaged state 3 months ago. Eng: engaged.
