Primary Outcome Measures

Name	Time	Method
Total Knowledge Score	Within 1 week after reviewing the decision aid	Six multiple choice knowledge items covered important facts patients should know about chest pain or discomfort and treatments. A total knowledge score (0-6) was created by summing the total number of correct responses. A missing knowledge response was marked as incorrect. Any survey with more than three missing knowledge responses did not get a total knowledge score. A higher score indicates higher knowledge on the topic. Both decision aids provided information for answering all knowledge items. Higher knowledge scores are better.

Secondary Outcome Measures

Name	Time	Method
Treatment Leaning (Percentage of Patients Who Have a Clear Treatment Preference)	Within 1 week after reviewing the decision aid	To determine the percentage of patients who have a clear treatment preference for their stable chest discomfort.
Satisfaction With the Intervention	Within 1 week after reviewing the decision aid	Number of respondents who rated the material as "very good" or "excellent".
