A Guide to Reproducibility in Preclinical Research.

Area of Science:

• Biomedical research
• Scientific reproducibility
• Research integrity

Background:

• Growing concerns regarding the "reproducibility crisis" in biomedical research.
• Need for a simplified guide to understand and address reproducibility issues.

Purpose of the Study:

• To distill complex discussions on reproducibility into an accessible guide.
• To facilitate a better understanding of reproducibility within and across studies.

Main Methods:

• Defining reproducibility within studies (internal consistency).
• Defining reproducibility across studies (external validation).
• Applying principles from clinical trials to preclinical research.

Main Results:

• Reproducibility involves obtaining identical answers from data analysis and similar conclusions from repeated experiments.
• Transparency and rigor are foundational elements for achieving reproducibility.
• Detailed protocols and proactive data management enhance research reliability.

Conclusions:

• Implementing transparent and rigorous practices is crucial for the biomedical field.
• Investigators should adopt strategies like pre-specified analysis plans and detailed protocols.
• Senior researchers play a vital role in fostering a culture of reproducibility.
