Cost-effectiveness analyses compare the value of different treatment strategies, given that one strategy is more effective but also more costly than the other. The results are often used as a pharmacoeconomic basis to support a particular treatment strategy. ⋯ Most published cost-effectiveness analyses regarding antiviral treatment of hepatitis B or hepatitis C reported favorable results. These results may suggest that researchers only attempt cost-effectiveness studies when there is a high likelihood of positive results. Regardless of the explicit cause of the bias, more awareness and scrutiny are needed when utilizing cost-effectiveness studies in decision making.
