Warfarin in the Prevention of Stroke Associated with Nonrheumatic Atrial Fibrillation (Original Article, N Engl J Med 1992:327;1406 - 1412) . On page 1409, in Figure 1, the solid line should have referred to the patients in the warfarin group and the broken line to those in the placebo group. We regret the error.
