• EUnetHTA: Endpoints used for Relative Effectiveness Assessment Composite endpoints. ^[39] This guideline provides a set of recommendations and aspects to be considered for the assessment and interpretation of results of composite endpoints while performing relative effectiveness assessments.
• EUnetHTA: Endpoints used in Relative Effectiveness Assessment Surrogate Endpoints. ^[40] This guideline is intended to provide guidance on when and how surrogate endpoints can be used for Relative Effectiveness Assessment (REA). The guideline is not intended to give a comprehensive list of validated surrogate endpoints and how well they predict final clinical endpoints.
• EUnetHTA: Endpoints used in Relative Effectiveness Assessment Safety. ^[41] This guideline aims at providing a framework for the evaluation of relative safety performed by HTA assessors in the context of Relative Effectiveness Assessment (REA) .
• EUnetHTA: Endpoints used for Relative Effectiveness Assessment Health related quality of life and utility measures. ^[42] This guideline encompasses “health-related quality of life” (HRQoL) measures used for assessing HRQoL as one of the patient-reported outcomes of an intervention targeting morbidity reduction as well as HRQoL measures used in combination with life expectancy. As such, it relates mainly to the use of HRQoL measures in clinical trials. The perspective taken is that of the assessor of the relative effectiveness of an intervention in the context of a reimbursement request.
• EUnetHTA: Comparators & Comparisons Criteria for the choice of the most appropriate comparator(s). ^[43] This guideline is intended to summarise the available literature, the advice provided by existing national guidelines and the information from current national practice on the choice of comparator, and to outline some of the challenges arising when establishing what the comparator for a specific assessment should be. It provides a set of internationally agreeable best practice recommendations for the selection of the most appropriate comparator when completing a REA.
• EUnetHTA: Comparators & Comparisons Direct and indirect comparisons. ^[44] This guideline is intended to describe the main methods of direct, indirect and mixed treatment comparison available in terms of the types of relationship they can model and the assumptions inherent in them. The guideline is not intended to give a detailed understanding of the meta-analytic techniques described, but rather to explain the main strengths and weaknesses of the methodologies. The guideline discusses some common issues in meta-analysis that must be considered when interpreting results. Finally, the guideline provides a set of recommendations regarding the use of direct and indirect comparisons in a relative effectiveness assessment (REA).
