NHC operates the following policy for making corrections to the print and online versions of their peer-reviewed content.

Publishable amendments 

That affect the publication record and/or the scientific accuracy of published information receive a DOI and are published in print and online in the journal. Four categories of amendments are relevant for peer-reviewed material: Erratum or Publisher Correction, Corrigendum or Author Correction, Retraction or Addendum. All four correction types are bi-directionally linked to the original published paper. Detailed information on each amendment category follows below.

Erratum or Publisher Correction

Notification of an important error made by the journal that affects the publication record or the scientific integrity of the paper, or the reputation of the authors or of the journal. 

Corrigendum or Author Correction

Notification of an important error made by the author(s) that affects the publication record or the scientific integrity of the paper, or the reputation of the authors or the journal.

Retraction 

Notification of invalid results that affect the reliability of a previously published article. The original article is marked as retracted but remains available to readers, and the retraction statement notifying readers of the invalidity of the published paper is bi-directionally linked to the original published paper.

Addendum

Notification of additional information about a paper. Addenda are published when the editors decide that the addendum is crucial to the reader's understanding of a significant part of the published contribution. Addenda include Editorial Expression of Concern, which is an editorial statement alerting our readership to serious concerns with the published paper. Editorial Expression of Concern are typically updated with another amendment once further information is available.

Editor's Note

An editor's note is a statement from editors notifying readers of issues related to the published paper. It is an online update made only to the HTML version of record of the published article. Editor's notes are typically updated with another amendment once further information is available. 

 

Withdrawal Policy

Some authors request withdrawal of manuscript from the publication process after submission. Withdrawing manuscripts from publication wastes the valuable resources and tremendous amount of effort made in processing the manuscripts by the editors, reviewers and the editorial staff.

Submission of an article to NHC implies that the work has NOT been published or submitted elsewhere; therefore, the journal is strongly against unethical withdrawal of an article from the publication process after submission. Once the article is submitted, the author grants the editorial board full publishing rights and it is the absolute right of the editorial board to decide on article withdrawals.

For genuine withdrawal, the corresponding author should submit a request which must be signed by all co-authors explaining the reason of withdrawing the manuscript. The request will be processed by the editorial board and only serious genuine reasons will be considered if possible. The decision of the editorial board will be final and not negotiable. If an author requests a withdrawal within 3 days of submission, the author is allowed to withdraw the manuscript without paying any withdrawal fee; however, if the author withdraws the manuscript any time after review and acceptance, a withdrawal fee of $10 will have to be paid.
