1) The document proposes using value of information (VOI) analysis to calculate the value of transferability (of results from a multinational trial to a specific country) in terms of expected value of sample information (EVSI). 2) It applies this method to results from the Scandinavian Simvastatin Survival Study, defining the posterior distribution of country results given the multinational trial results. 3) The value of transferability is measured as the difference between the prior and posterior expected value of perfect information (EVPI) for each country, indicating whether the multinational trial results reduce or increase uncertainty for reimbursement decisions.
