Late-Breaking Abstracts

The focus of Late breaking abstracts is placed on capturing abstracts with ground-breaking and unique data that would not otherwise have been presented at WCN’21. If you have data available for submission only after the regular abstract deadline, the Scientific Program Working Group would be interested to receive your submission and consider it for presentation.

Late-breaking abstracts describe the latest advances, trial data, and results that have not been previously published or presented and highlight novel and practice-changing studies. Late-breaking abstracts contain ground-breaking and unique data.

The call for late-breaking abstracts is NOT an extension of the general submission deadline. The submission period is from May 29, 2020, to February 10, 2021. Late breaking abstract submitters are required to submit a ‘place holder’ abstract during the regular submission period (deadline November 30, 2020). For further information regarding updating your abstract please see section Post-Submission here below.
