†The abbreviation US may be used without expansion at first mention or inclusion in the abbreviations list only when it is used as a modifier and only when it directly precedes the word it modifies. In other instances, United States should be used.
‡Abbreviate on first mention in AJVR only. In JAVMA, expand this term on first mention and include it in the abbreviations list if used at least 3 times, if the authors desire.
§Although this abbreviation can be an adjective or a noun, it cannot be used to mean magnetic resonance image. The term MRI image is acceptable.
║In AJVR, PBSS may be used without expansion on first mention, or it may be expanded to PBS solution and used as such throughout the report; it is the authors’ choice. In JAVMA, PBSS should be expanded on first mention and included in the abbreviations list if used at least 3 times.

Exceptions: a division of time appearing in a table column heading should be spelled out, unless the division is in parentheses. Similarly, a division of time should be spelled out when used in a figure axis label, unless the division is in parentheses. In such parenthetical expressions, the abbreviation should be used.
