Guidelines on statistics for researchers using laboratory animals: the essentials.

Area of Science:

• Biostatistics
• Animal Research Ethics
• Experimental Design

Background:

• Growing concern over flawed statistics and poor reproducibility in animal research.
• Ethical implications of animal waste due to deficient research practices.

Purpose of the Study:

• Provide biostatistics guidelines for researchers in animal experimentation.
• Address frequent statistical mistakes, misuses, and misconceptions.
• Improve the design, execution, and reporting of experiments.

Main Methods:

• Review of common statistical errors and misconceptions in animal research.
• Formulation of twelve practical recommendations for researchers.
• Focus on specific challenges within animal experimentation.

Main Results:

• Twelve key recommendations covering sampling, sample size optimization, statistical test selection, p-value interpretation, and results reporting.
• Identification of critical statistical issues for researchers to consider.

Conclusions:

• Implementing these biostatistics guidelines can enhance the quality and reproducibility of animal research.
• Reducing flawed statistics minimizes unethical animal waste.
• Promoting sound statistical practices is crucial for ethical and effective scientific inquiry.
