Decision tree for administration of treatment. In this figure, p = P(D +) is the probability associated with the presence of a disease; 1 - p = P(D -) is the probability associated with the absence of the disease; U i , i [1,4], are the utilities corresponding to each outcome. Note that we use the term "treatment" in the generic sense of health care intervention, which may indicate therapy, procedure, or a diagnostic test.
