In the 2011 TCT conference trial by Dr. Makam, what percentage of participants were diabetic?

• A. 39%
• B. 50%
• C. 57%
• D. 46%

Answer: (B)

Diabetes status among participants is a key baseline characteristic because it affects risk and how patients respond to interventional treatments. In this trial, about half of the participants were diabetic, meaning the prevalence was 50%. This balance helps ensure the study population resembles real-world practice where diabetes is common, and it also allows comparisons of outcomes between diabetics and non-diabetics within the same trial. Since diabetes is linked to higher complication and restenosis risks, having 50% diabetics shapes how the results are interpreted and to whom they apply. The other percentage options don’t match the reported baseline, so they aren’t representative of this study’s diabetic prevalence.
