Fig. 3From: The impact of demographic changes, exogenous boosting and new vaccination policies on varicella and herpes zoster in Italy: a modelling and cost-effectiveness studyBox plots of the posterior distribution of the NMB (with 2.5%, 25%, 50%, 75%, and 97.5% quantiles) obtained, under the PSA, from the comparison between each policy and the no intervention scenario, using the conservative supply-based threshold t of 15,000 EUR, under model TI (a and c) and model PI (b and d), and under the longest time horizon (85Â years). Discount rates for both costs and benefits are assumed to be equal to 0% (a and b) and to 3% (c and d). Net benefit charts of the NMB obtained under different CE thresholds and under the longest time horizon (85Â years), for e model TI and 0% discount rate; f model PI and 0% discount rate; g model TI and 3% discount rate; h model PI and 3% discount rateBack to article page
