- Headings. Use ALL CAPITALS to indicate major sections of a paper, and Initial Capitals to indicate subsections.
- SI units. Include SI units in parentheses after conventional units (see http://jama.ama-assn.org/misc/auinst_si.dtl(jama.ama-assn.org)).
- Measurements. Do not put periods after metric measurements (e.g., 3.5 mmol per L, 11.6 mg per kg).
- Numbers. Spell out numbers one through nine. Use numerals for 10 and higher. Exception: Always use numerals in dosages, percentages, degrees of temperature, and metric measurements.
- Drug names. Use the generic name for all drugs. Include the trade name in parentheses after the first mention of a drug in the text. Trade names used in AFP are the first brand approved. If a drug is not available in the United States, indicate so in parentheses after the name.
- Abbreviations. Except for units of measurement, abbreviations are discouraged. When first used, an abbreviation should be preceded by the words for which it stands.
- Percentages. Use the percent sign (%) rather than the word “percent."
- Style questions. For questions about medical writing style, consult the American Medical Association Manual of Style.1
- Formatting text. Note the following general text formatting guidelines: (1) do not justify the right margin; (2) do not use bold print or italics; and (3) use a single, standard typeface of letter quality, such as Times New Roman or Arial 12 point.
