Decision tree used to represent the relationships among the variables important to monitoring strategy decisions. The decision maker may choose between the four EEG monitoring strategies (no EEG, 1 hour EEG, 24 hours EEG, or 48 hours EEG). For a given patient, electrographic seizures may or may not occur. Depending on the duration of EEG monitoring, the electrographic seizures may or may not be identified. The square signifies the choose node, circles signify the chance nodes, and triangles signify the terminal nodes.
