Each day, patients and their physicians make treatment decisions with access to only a fraction of the relevant clinical research data. Many clinical studies, including randomized clinical trials, are never published in the biomedical literature.1,2 Among those that are published, key information is often not presented, such as data on specific outcomes and safety end points.3,4 Moreover, patient-level data from clinical trials are rarely publicly available, leaving investigators to conduct meta-analyses of summary-level data, an approach with limitations.5
