Correspondence items are limited to 1000 words and can include a brief table or a figure plus citations. The authors of the original article will be allowed to respond to the correspondence provided they do so within two months. The response is subject to the same length limitations as the comment. Correspondence on previously published correspondence will not be considered. Personal invective in correspondence will not be tolerated.
Correspondence is occasionally peer-reviewed at the option of the editor.
When a correction must be made, it should be done quickly. Delay only increases the likelihood of propagation of the error. The decision rests with the Editors. Last updated November 17, 2000.
