The answer to Question 6 in the July 1998 “Clinical Quiz” (page 34), pertaining to the article “Indications for Anticoagulation in Atrial Fibrillation” (page130), is incorrect as the question is currently worded. The correct answers to the question as it is published are B and C. However, if the scenario had involved a patient 75 years of age, the answer might more clearly be C alone. Medication in the 65-to 75-year-old age group has been a point of controversy, and most physicians preferentially choose warfarin over aspirin unless there is a contraindication to its use.
