The Anticoagulation and Risk Factors in Atrial Fibrillation (ATRIA) Study demonstrated that a 5-point risk stratification scheme (ie, anemia, severe renal disease, age, prior bleeding, and hypertension) was effective in quantifying the risk for major hemorrhage among patients with AF receiving warfarin.
Erta Ale (or Ertale or Irta'ale) is a continuously active basaltic shield volcano in the Afar Region of northeastern Ethiopia. It is situated in the Afar Depression, a badland desert area spanning the border with Eritrea. Erta Ale is the most active volcano in Ethiopia.
