Use this form to change model values before carrying out a sensitivity analysis, Markov analysis, or Monte Carlo simulation. All inputs will be validated against a range specified in the model. Changes can be made to model values without choosing an analysis by clicking on the Validate button, rather than an analysis button.

This model's baseline values suggest cryopreserved homografts as the optimal strategy. To see a change in the optimal strategy, try using this form to first increase the baseline values for the probability of hemorrhage, thromboembolism, and/or valve thrombosis in the cryopreserved homograft strategy. Then, perform a sensitivity analysis on any of the other parameters in the model.
