^aThe currency exchange rate was 1.000 USD = 6.357 CNY at the time the screening program was performed
Detection cost = cost3/number of cases, cost ratio = detection costs for scenarios B, C, D, E, F and G/detection cost of scenario A
*Cost Ratio= cost of scenario B, or C,or D, or E, or F, or G/ cost of scenario A
