In the article beginning on page 738 in the October 2021 issue, the green-shaded area in figure 1 should be labeled “Intrinsic” and the yellow-shaded area should be labeled “Extrinsic.”
Coagulation cascade with common anticoagulant agent targets. The intrinsic (green), extrinsic (yellow), and common (purple) pathways of the coagulation cascade are highlighted. The targets of anticoagulant agents (gray boxes) and denoted by red dashed lines with boxed ends. In general, tests using activators to stimulate the cascade at, or proximal to, the drug target will be affected by the drug. Coagulation factors are shown in roman numerals. AT, antithrombin; DTIs, direct thrombin inhibitors; VKAs, vitamin K antagonists.
