interpreting how much data has been lost by analyzing dbcc output
Scanning through the output rather quickly, looks like you lost about 1,045 pages (so 1045 x 8192 bytes). I did this simply by performing a find for "has been deallocated" in the pastebin and seeing how many occurrences of that term were discovered - 1,039. Then I searched for "actual 0:0" and that yielded 6 more pages that weren't found.

No way to guess how many rows that represents. But not sure how that helps you anyway - whether you lost 100 pages or 1,000 pages, or 800 rows or 8,000 rows, what are you going to do with this information?

Whether you can find any more detailed information about the actual data from the transaction log depends on a couple of things, e.g. what recovery model are you in, why were there no backups (because they were on the same drive or because none had ever been taken), and how good are you with a hex editor?
