Source of Diagnosis and Verification of CVD From 2001 to 2013, by DES Exposure Status
| Variable | DES-Exposed (n = 3941) | DES-Unexposed (n = 1705) | Total |

| Verified CVD including deaths (n) | |||
| CAD | 28 | 12 | 40 |
| MI | 18 | 5 | 23 |
| Stroke | 12 | 8 | 20 |
a
CVD events from the questionnaire included CAD, MI, and stroke.
b
Probable CVD was included only with total CVD, and not with individual CVD events in the data analysis.
c
Participants can have more than one type of event (i.e., CAD, MI, stroke), so number of events is larger than the number of participants.
