Taking parameter values as baseline values (Table 2), the results for the first four case-finding scenarios compared with the current do nothing (no HCV case-finding in prisons) strategy: a) the undiscounted annual cost of implementing each case-finding scenario, b) the undiscounted annual number of new HCV cases identified when implementing each case-finding scenario, c) the cumulative average cost per new HCV case detected with discounting, d) the proportion of those RNA positive that are identified over time.
