Figure 2From: Treating childhood pneumonia in hard-to-reach areas: A model-based comparison of mobile clinics and community-based care Decision tree: transitions from the healthy state. Healthy children may remain healthy or transition to any of the disease states on the following day. If a child develops pneumonia and health care is both available and sought, the child transitions directly to treatment for pneumonia; otherwise, the child transitions to a disease state (non-severe or severe pneumonia) without treatment. Values and equations defining transition probabilities are detailed in the Appendix.Back to article page
