Note:
a
In this context, “utility” is a number that represents the value a respondent associates with specific CAT regimen characteristics. A higher absolute value for utility indicates a greater rating of importance for the specific characteristics.
Abbreviations: CAT, complex antithrombotic therapy; MI, myocardial infarction; CVA, cerebrovascular accident; ICH, intracerebral hemorrhage; UGIE, upper gastrointestinal event.
