Conflict of Interest (COI)
A conflict of interest exists when professional judgment about a primary interest (patient welfare, research validity) may be influenced by a secondary interest (financial gain, career advancement).
1Detailed Explanation
COI disclosure is a cornerstone of research integrity. Financial COIs include: consulting fees, honoraria, stock ownership, patents, grants from industry. Non-financial COIs include: personal relationships, academic competition, intellectual beliefs. ICMJE requires COI disclosure for all authors, not just the corresponding author. COI statements are published with the article. Many journals use the ICMJE COI disclosure form. COI management strategies include: disclosure, recusal from decisions, independent statistical analysis, and independent data monitoring. Failure to disclose COIs has led to high-profile retractions. Funding sources should also be disclosed. Some journals prohibit certain industry relationships for authors.
2Examples

- B.Funding statement: 'This study was funded by the National Institutes of Health (R01HL123456). The funder had no role in study design, data collection, or analysis.'
3Why It Matters in Research
COI disclosure is mandatory at all major medical journals and at most conferences. Transparency about COIs maintains public trust in medical research.
