Figure 2. AHP decision model with optional variations showing different perspectives and how to explore the effects of uncertainty.

Figure 2

Footnote: The basic AHP model is shown in the clear boxes on levels 1, 3 and 4. The model can be enlarged to explore the effects of different perspectives by performing separate analyses from different points of view. This is illustrated by adding the upper part of the shaded boxes on level two. In this model separate analyses would be performed from the perspective of both the patient and the clinician. Similarly the model can be enlarged to explore the effects of future uncertainty. This is illustrated using the lower part of the shaded boxes on level 2. This model would compare the options under two different scenarios: benign disease and aggressive disease. See text for further details. Abbreviations: Admin = Ease of Administration.
