Preclinical Research Reporting in Shock: Room for Improvement.


Reynolds PS, Garvan CW
Shock. 2020 May 14.
PMID: 32941386.


THE ARRIVE (Animals in Research: Reporting In Vivo Experiments) guidelines were endorsed by the Shock Society in 2012, but to date there has been no systematic evaluation of research reporting quality for Shock. We systematically assessed 100 randomly selected animal-based research articles published between 2014 and 2018 for reporting quality and statistical practice, compared to 40 pre-ARRIVE studies. More than half of surveyed papers omitted verifiable ethical oversight information and basic animal descriptive information. Few papers reported best-practice methods, such as sample size justification (10%), randomization (43%), randomization method (7%), blinding (23%). Only one paper reported effect sizes to interpret study results. Most troubling was inadequate reporting of welfare-related information (anesthesia, analgesia, humane endpoints, euthanasia). Almost a decade after ARRIVE endorsement, our findings show that reporting deficiencies have persisted with little sign of correction. There is a clear need for investigators to increase transparency of research methods reporting, and drastically improve skills in experimental design. Improvement in standards and greater attention paid to reporting will lead to improvement in reproducibility, replicability, and research quality. It is incumbent upon the research community to improve reporting practices; accurate and transparent reporting is integral to producing rigorous and ethical science.
