  • Stephan Moll, MD writes…  The more than 20 chapters and 801 pages of the respected 2012 ACCP Antithrombotic Therapy Guidelines – beautifully evidence-based, but always very cumbersome to read for the clinician looking for quick management guidance -, have now been summarized by the ACCP into a visually appealing, uncluttered, clinician-user-friendly document, referred to as
