Validity of original studies in health technology assessment reports: significance of standardized assessment and reporting.

Objectives: As health technology assessments (HTA) may have considerable impact on health-care decisions, it is essential to guarantee the expected quality of these assessments. Variations in the methods used or lack of transparency can affect the important role of HTA reports.

Methods: In our study, we analyzed the methods used in two corresponding HTA reports to assess the validity of two key papers, which were included in both reports.
