Issues surrounding authorship, acknowledgments, publication policies, disclosure of bias and interests and handling misconduct allegations are common to all kinds of research, regardless of methodology or content. When research involves large teams, publication committees with clear policies about these topics are the norm. Whatever the arrangements, they should be spelled out in advance and procedures to resolve conflicts need to be in place. Best practices can be identified by consulting institutional policies, professional societies’ ethical codes, and the uniform guidelines of the International Committee of Medical Journal Editors
Investigators should agree early in their research planning who does what and who will be authors.
