Pre-Press and Proofs

Proofs are prepared by our typesetters, Thomson Digital, and will be sent to the authors a few weeks after acceptance (typically 4-6 weeks). The corrected proofs will be placed in our online contents and indexed in PubMed as "Epub ahead of print" article after corrections are received from the authors. The pre-press article is fully citable by using the DOI number. This is not the final version. When the article is published in an issue, the final, updated version replaces the pre-press version.

The corresponding author will receive a PDF of the proofs and is asked to check the proofs 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. Please be sure to return your corrections as quickly as possible.

Note: Any changes to authors or title after acceptance should also be sent to the editorial office ( so our records 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 see our instructions to authors for more information (
