Pre-Press and Proofs

Accepted articles will be placed online and indexed in PubMed as "pre-press" articles a few weeks after acceptance. This process will occur around the time the authors receive proofs. The pre-press file is the uncorrected proof and will be replaced by the final corrected version of the article at the time of final publication.

The corresponding author will receive a PDF proof and is asked to check this proof carefully (the publisher will execute a cursory check only). Corrections other than printer's errors, however, should be avoided. Costs arising from such corrections will be charged to the authors.

Note: Any changes to authors or title after acceptance should also be sent to the editorial office ( so the disclosure listing can be updated. After acceptance, any additions or deletions to the list of authors MUST be approved by the Editor-in-Chief, and all authors on the manuscript must also sign off on the changes. Please contact the Managing Editor ( for more information.
