What is 'Persuasive Data'?

I'm submitting an abstract for the World Molecular Imaging Conference and they advise:

Please include a Persuasive Data file if you would like your abstract to be considered for an oral presentation. Persuasive data should include figure captions that explain the results of the figure without requiring the reviewer to re-read the main text.

The Persuasive data file should be .pdf or .doc

I have never come across this format before, does anyone know what a persuasive data file is? I'm guessing either extended abstract or actual experimental data?
