Some additional information about Edoxaban has been added to the Other anticoagulants page (although it is not licensed in Australia and does not appear to have any advantage over rivaroxaban or apixaban), as well as a variety of small changes to information about the other NOACs.
A good recent open access review article on the subject is: Pollack, CV. Coagulation assessment with the new generation of oral anticoagulants. Emergency Medicine Journal 2015 .
