The international register of Meta-Research (IRMR) is a free, open access database of prospectively registered meta-research studies in healthcare.

Meta-research has been defined as the study of research itself including research methods, reporting, reproducibility, evaluation and incentives. As research on research, meta-research uses scientific methods to explore how research is done and interpreted, with the goal of verifying the validity of research techniques and improving the reliability of conclusions.(1)
