A primer on incorporating sex as a biological variable into the conduct and reporting of basic and clinical research studies.

The recent move to require sex as a biological variable (SABV), which includes gender, into the reporting of research published by the follows a growing, and much-needed, trend by journals. Understandably, there is concern over how to do this without adding considerable work, especially if one's primary research focus is not on elucidating sex/gender differences. The purpose of this article is to provide additional guidance and examples on how to incorporate SABV into the conduct and reporting of basic and clinical research. Using examples from our research, which includes both studies focused and not focused on sex/gender differences, we offer suggestions for how to incorporate SABV into basic and clinical research studies.
