Dero,
Nice article; thanks for sharing. Noticed NATT received a plug under the source page.
I am reading a book called the Coumadin/Warfarin Help Book (see http://www.amazon.com/Coumadin-Warfarin-Help-Book-Anticoagulation/dp/0979356423) . The author, Diana Schneider, sent me a courtesy copy for reading and asked me to provide any inputs/updates that she should include in the next revision of this book. It's a nice book written for patients and though there are some discrepancies (statistical and not enough information about thrombophilia) it doesn't take away from the purpose of the book (to help patients understand what coumadin/warfarin is and why it is used).
