Conventional units of measure are preferred, with SystèmeInternational (SI) units expressed secondarily (in parentheses). In tablesand figures, a conversion factor to SI may be presented in the footnote orlegend to economize space. Exceptions to this policy include calories, hematocrit,glycosylated hemoglobin, blood cell counts, and ejection fraction, for whichconventional units alone should be expressed. The metric system is preferredfor length, area, mass, and volume. (See SI conversion table.)
Use generic names of drugs, unless the specific trade name isdirectly relevant to the study design or discussion.
Do not use abbreviations in the title or abstract. Limit theiruse in the text.
Do not use footnotes or appendixes. Such materials should eitherbe incorporated into the text or offered to interested readers on request.
Include a statistical analysis section under Methods that fully describes the application of each statistical procedureused. If a test is used that is not commonly presented in the ARCHIVES, brieflydescribe its purpose and how it is to be interpreted. Results should reportthe test statistic (eg, χ2, F or t value),degrees of freedom, and P value or confidence limits.Measures of central tendency (eg, means) should be accompanied by measuresof variability (eg, SDs). In the cover letter, state the name of your statisticalconsultant, if appropriate.
Acknowledge all illustrations or tables adapted or reproducedfrom other publications and submit written permission to reproduce (in printand online) from the original publishers. (See permission form.)
Tables and figures should provide substantive data and not merelyillustrate the text. While the main finding of a table or figure may be discussedin the narrative, the table or figure should not duplicate the text. Althoughno specific guideline can be applied to all articles, the number and lengthof tables and figures should be kept to a minimum.
