Decision analysis tree for composite tissue allotransplanta-tion of the face, including adjusted probabilities and quality-adjusted life years for each health state (pathway). The probabilities of each health state, as determined from the literature (Table 1), were first modified such that the probabilities resulting from a chance node add up to 1.0, providing the adjusted probability.
