Comments policy

You can comment on all articles published in our journals. To make use of this feature, follow the 'Post a comment' link in the right-hand side of any article abstract or full text. If comments have already been posted on an article there will be a link to them here too.

To post a comment you need to be a registered user and to verify your email address. Verification is a one-time only process - when you first try to post a comment you will be sent a verification email to your registered email address. Click the link in the email and your address will automatically be verified and you can continue with your posting. Our comment system is moderated to prevent abuse, but you will receive a prompt decision on your comment and it will appear on the site immediately on acceptance.

BioMed Central reserves the right to decline to post a comment if in its absolute discretion it believes it would be inappropriate to do so, and reserves the right to remove a comment at any time.

Comments will not be accepted if they appear to be indecent, offensive, or contain negative content of a personal, racial, ethnic, sexual orientation, or religious character. We will not post comments that appear to be libellous or otherwise legally problematic.

BioMed Central will also not accept comments that present evidence suggestive of the need for changes in practice or thinking in terms of preventive or therapeutic interventions, if that evidence has not previously been published in a peer-reviewed journal. We will not post comments that give information on individual patients.

Comments which may also be refused are those that:

  • are irrelevant to the article;
  • are trivial;
  • appear to be advertising;
  • are a repetition of comments posted elsewhere on BioMed Central;
  • are not in English;
  • are badly written or incomprehensible.

We cannot include figures, tables or equations within a comment, although hyperlinks may be included. If your response is substantial then you may wish to consider submitting an article - in this case you should discuss this with the editorial office.

BioMed Central asks that anyone posting a comment complete a competing interests declaration.

Competing interests policy

A competing interest exists when your interpretation of data or presentation of information may be influenced by your personal or financial relationship with other people or organizations. Those who post comments should disclose any financial competing interests but also any non-financial competing interests that may cause them embarrassment if they were to become public after the publication of the comments.

When completing your declaration, please consider the following questions:

Financial competing interests

  • In the past five years have you received reimbursements, fees, funding, or salary from an organization that may in any way gain or lose financially from the publication of this comment, either now or in the future?
  • Do you hold any stocks or shares in an organization that may in any way gain or lose financially from the publication of this comment, either now or in the future? If so, please specify.
  • Do you hold or are you currently applying for any patents relating to the content of the comment? Have you received reimbursements, fees, funding, or salary from an organization that holds or has applied for patents relating to the content of the comment? If so, please specify.
  • Do you have any other financial competing interests? If so, please specify.

Non-financial competing interests

Are there any non-financial competing interests (political, personal, religious, ideological, academic, intellectual, commercial or any other) to declare in relation to this comment? If so, please specify.

If you are unsure as to whether you have a competing interest please discuss it with the editorial office.
