A group of systematic literature reviews is under way to collate all available evidence on which outcomes of Alzheimer’s disease (AD) are most important, and what constitutes a meaningful delay in its progression, from the perspectives of people with AD, their carers and healthcare professionals. A series of distinct but internally consistent, sensitive searches were undertaken to capture a broad evidence base. Specific inclusion criteria were applied to refine this to a coherent, relevant subset of information which answers our research questions. ROADMAP members of WP2 have screened and are now quality appraising full-text papers in preparation for data extraction and synthesis.
