Introduction: An objective of the Meta-AnalyTical Interagency Group (MATIG) is to conduct patient-level meta-analyses of cardiovascular outcomes using data from publicly available repositories. We describe challenges with data re-use from a seminal trial, provide a systematic approach to identify and curate data elements for hypothesis generation, and establish stackable trials to support these analyses. Methods: We used data from the ACCORD trial to assess risk factors and their gender specific differences for the event of hospitalization or death due to heart failure (hdHF), in patients with type 2 diabetes*. We identified the data elements needed to answer the research questions, reviewed the trial protocol to verify definitions, extracted patient-level data, performed quality assessment and statistical analysis. The results showed a gender difference in the effect of intensive vs. standard glucose-lowering therapy on hdHF. To validate the findings, we sought additional trials in BioLINCC to develop a compendium for meta-analysis, and repeated these steps for each trial. Results: Challenges for reusing the ACCORD trial included access to complete patient-level data and metadata. The compendium, developed to evaluate the stackability** of data across trials, identified differences in trial designs, patient populations, study interventions, and data elements that may impact the feasibility and interpretation of meta-analysis. An example of compendium components is shown in Table 1. Conclusion: High-quality metadata facilitate re-use of trial repository data. This compendium standardizes common data elements for gender, racial and age-group specific outcome assessment in major clinical trials. It provides the framework to assess the fitness of trials for patient-level meta-analyses. Efforts are underway by MATIG to expand the compendium to include risk factors and major cardiovascular outcomes across multiple large trials for meta-analysis.
