1 Answer to this question

Here are the responses to your questions:

  • There is no particular time frame for declaring conflict of interest on your manuscript. If you have nothing to declare, you can just add the following sentence for a research article “Authors have no conflict of interest to declare”. But if you feel there could be a potential conflict of interest with a company where you had been working in teh past, it is best to disclose it, even if it was 5 years ago.
  • Even if the funding amount that was received from a sponsor was very small, you must mention it in the disclosure of conflict of interest statement.
  • Disclosure of profits of the sponsor company is not necessary in your manuscript.
