Key Considerations When Writing Your Own:
* Specificity: Be precise about each author's role. Avoid vague terms like "contributed to" without further explanation.
* Accuracy: Each statement must accurately reflect the individual's involvement.
* Completeness: All authors should be listed and their contributions described.
* Consistency: Use consistent language and structure throughout the statement.
* Journal Guidelines: Check the specific guidelines of the journal you are submitting to, as they may have specific requirements for author contribution statements.
Remember to replace A., B., C. etc. with the actual authors' names. The level of detail needed will vary depending on the complexity of the project and the journal's requirements.
