The American Society for Pharmacology and Experimental Therapeutics updated journal guidelines for data analysis and reporting. These changes emphasize detailed descriptions of experimental methods and results for more transparent research.
Area of Science:
- Pharmacology and Experimental Therapeutics
- Biomedical Research Reporting
Background:
- The American Society for Pharmacology and Experimental Therapeutics (ASPET) has revised author instructions for three key journals: Drug Metabolism and Disposition, Journal of Pharmacology and Experimental Therapeutics, and Molecular Pharmacology.
- These revisions focus on enhancing the granularity and transparency of data analysis and reporting, not on experimental design or execution.
Discussion:
- Key recommendations include distinguishing between preplanned and exploratory studies, specifying statistical analysis plans before data collection, and clearly documenting outlier exclusion criteria.
- The guidelines advocate for reporting variability using standard deviation (S.D.) or interquartile range and precision with confidence intervals, discouraging the use of standard error (S.E.).
- Emphasis is placed on reporting effect sizes with confidence intervals over P values, and on using data visualization methods like scatter plots, violin plots, or box-and-whisker plots instead of bar graphs where appropriate.
Key Insights:
- Revised guidelines promote greater detail in reporting experimental findings and statistical methods.
- The changes aim to reduce bias and increase the transparency of published research.
- Clearer reporting standards will improve the reproducibility and interpretability of scientific studies.
Outlook:
- Implementation of these revised guidelines is expected to elevate the quality and reliability of research published in ASPET journals.
- These standards may influence reporting practices across broader scientific disciplines.
- The focus on detailed reporting will empower researchers to better understand and build upon existing findings.
