A-Cases prevented denotes cases prevented from being imported into the U.S. by active overseas screening programs;
B-U.S. perspective savings or costs represents the total projected costs or savings in the U.S. with overseas screening programs;
C-The incremental cost-effectiveness ratio is from the combined perspective which combines both overseas and foreign costs;
