Which of the Thrawn audiobooks are abridged?

I'm in love with the thrawn books, but I'm really enjoying the audio versions as Marc Thomson's voice fir Thrawn is, well, mouth-watering.

BUT I saw on a post here somewhere that some of the audiobooks are abridged, but audible doesn't say which on the title page.

I don't want to miss out anything from these books, so I'm prepared to read them, but to save money I'd just like to know which Thrawn audiobooks are abridged so I know which books to buy.
