|| “Selection and Description of Participants:
• Because the relevance of such variables as age and sex to the object of research is not always clear, authors should explain their use when they are included in a study report; for example, authors should explain why only subjects of certain ages were included or why women were excluded. The guiding principle should be clarity about how and why a study was done in a particular way. When authors use variables such as race or ethnicity, they should define how they measured the variables and justify their relevance.
• Where scientifically appropriate, analyses of the data by variables such as age and sex should be included” (CMAJ Editorial Policies).

|| Editors recommend (Editorial 2014):
1. Design studies that are sufﬁciently powered to answer research questions both for males and females (or men and women) if the health condition being studied occurs in both sexes/genders.
2. Provide sex- and/or gender-specific data where relevant in all clinical, basic science, and epidemiological studies.
3. Analyze the inﬂuence (or association) of sex or gender on the results of the study, or indicate in the Patients and Methods section why such analyses were not performed, and consider this topic as a limitation to cover in the Discussion section. Readers need to know whether the results generalize to both sexes/genders.
4. Indicate (if sex or gender analyses were performed post-hoc) that these analyses should be interpreted cautiously because they may be underpowered (leading to a false conclusion of no difference). If there are many such analyses, indicate that they may lead to spurious significance, and an erroneous conclusion of a sex- or gender-related difference.
|"The strain (when appropriate) and sex of animals used must be indicated. If both males and females were used, the numbers of animals from each sex must be indicated, and it must be indicated whether sex of animal was considered a factor in the statistical analysis of the data. Likewise, the sex from which primary cell cultures or tissues were obtained must be indicated. The authors are also encouraged to include sex of cell lines. If cells or tissues from both sexes were used without regard to sex, this should be indicated" (Instructions to Authors for Endocrinology— Manuscript Preparation, Materials and Methods).

||"If the research study was specific to one sex/gender, the reasons for this should be clearly stated [...] submitting authors are strongly encouraged to include data disaggregated by sex (and, whenever possible, by race) and provide a comprehensive analysis of gender and racial differences. The authors should include the number and percentage of men, women and, if appropriate, transgender persons who participated in the research study. Anatomical and physiological differences between men and women (height, weight, body fat-to-muscle ratios, cell counts, hormonal cycles, etc.), as well as social and cultural variables (socio-economic, education, access to care, etc.), should be taken into consideration in the presentation of data and/or analysis of the results (Journal of the International AIDS Society—Author Guidelines).

"At the Journal of Neuroscience Research we recognize that sex fundamentally influences the brain and have now established policy requiring all authors to ensure proper consideration of sex as a biological variable. These are as follows:
1. Any paper utilizing subjects (cells, animals, humans) of only one sex must state the sex of the samples in the title and abstract of the paper, with the obvious exception of sex-specific issues (e.g., prostate or ovarian function). Authors must also state the rationale for using samples from one sex rather than from both.
2. All papers must clearly state in the methods section the number of samples/subjects of each sex used in the research. For cellular work, the sex of origin of cells used should be reported in most cases. If cells or tissue from both sexes were used without regard to sex, this fact should be indicated.
3. JNR is particularly interested in experiments involving both male and female subjects studied at the same time, and with sufficient sample size to ensure meaningful statistical comparisons. The inability for any reason to study sex differences where they may exist should be discussed as a study limitation.
4. Manuscripts reporting exploratory analyses of potential sex differences in studies not explicitly designed to address them are encouraged. JNR understands the real risk of false-positive errors associated with subgroup analysis, but that risk is balanced by the equal or greater risk of false-negative errors resulting from a failure to consider possible sex influences. JNR also understands that false negative results may result from underpowered analyses, but given the dearth of such analyses in neuroscience to date, and the now clear imperative to change the status quo on this issue, explicitly exploratory analyses are called for in many circumstances.
5. Clinical work should be designed with stratified randomization by sex. Post hoc analyses may also be useful, again perhaps explicitly designated as exploratory.
