During the submission process, you will be asked to select 2 tiers of general topics for your abstracts to help us with the review and assignment process.

• Tier 1: General topics^*
• Tier 2: Sub-topics^*

^*See lists further below.

Abstracts must be comprised of four distinct sections:

• Introduction: Describes previous research and the rationale for the current study
• Methods: Describes how the study was conducted
• Results: Describes the results of the study
• Conclusion: Summarize the study and discusses its implications

Please do not insert tables into the body of the abstracts. They will need to be uploaded into jpg, png or gif as a figure.

All abstracts must be submitted electronically through the Congress management system.

• Abstracts should be submitted only in English and there is no fee for submission.
• The abstract allows a maximum of 10 authors and corresponding affiliations. If your research includes more than 10 authors, please provide additional details in the study group list and limit the author list in the abstract to those who were primarily involved in the research.
• The abstract text body is limited to 3,000 characters including spaces (about 400 words or more, depending on spacing).
• Please do not insert tables into the body of the abstracts. They will need to be uploaded into jpg, png or gif as a figure. A maximum of two figures (in JPG, GIF or PNG with ideally 600 dpi) can be included. These will not count toward the word limit, nor will the information about authors, institutions and study groups. File size of 2 MB maximum for each figure. Make sure you submit your figure with no surrounding white space and the text is readable.
