"Effectiveness/benefits: The current analysis represents an update of earlier work by the authors. However, they did not describe the main characteristics of the previous study or the sources used to derive the clinical data. Thus, it is not possible to judge the validity of these clinical estimates. The authors justified the selection of QALYs as the summary benefit measure by stating that they are a validated measure, which allows cross-disease comparisons. The utility weights were taken from a published US study due to the lack of Taiwanese data."
