*Lipid-lowering medications included statins (3-hydroxy-3-methyglutaryl-coenzyme A [HMG-CoA] reductase inhibitors) and nonstatins. The model for these medications was restricted to data from 1992 to 1998. †Antiplatelet medications included cyclooxygenase inhibitors (e.g., aspirin) and adenosine diphosphate (ADP) receptor inhibitors. .
