Sex As a Biological Variable

NIH expects that sex as a biological variable (SABV) will be factored into research designs, analyses, and reporting in pre-clinical and clinical studies. Accounting for SABV helps interpret and validate research findings, as well as enhances the rigor, reproducibility, and applicability of biomedical research. But how exactly do you account for SABV?

Reporting the Results of Valid Analyses

For decades, NIH has required valid analysis, also known as stratified analysis, to explore how well interventions work across sex/gender and race/ethnicity for all applicable clinical trials. After revising the policy last year, NIH now requires the findings from these stratified analyses to be reported on ClinicalTrials.gov after an applicable NIH-Defined Phase III clinical trial has completed. Wondering about how this impacts your research?

Understanding the Definition of a Clinical Trial and What That Means for You

A new “All About Grants” podcast is now available! In “Understanding the Definition of a Clinical Trial and What That Means for You”, Dr. Mike Lauer, NIH deputy director for extramural research, discusses the changes to clinical trial policies, addresses community questions, and speaks to how these changes will impact applicants and grantees.
