Hi David,
The BEST method is to go back to the author and ask them for a copy of the original document in Word format.
There are a bunch of tools out there to convert PDFs to Word, and they all do a decent job, but I have yet to find one that is perfect every time. Some miss styles, others miss special characters like '±'. Some mess w the figures, or omit styles. They all resulted in a Word doc that needed to be painstakingly proofread and massaged.
Ask for the Word version!
On rare occasions I've been told no, but after explaining why it was a genuine request, they always came through.
If you absolutely can't get them to budge, I'd use Adobe Acrobat Pro to convert it to Word and then carefully walk through both versions comparing them side by side
