Task: Answer Verification
Input (English): Question: Is osteoprotegerin associated with angiographic coronary calcification?
Answer: Both calcified and non-calcified culprit plaques exhibited a similar inflammatory response to stent-mediated injury. After PCI, osteoprotegerin decreased while proinflammatory cytokines increased, which may be consistent with a counterregulatory role for osteoprotegerin.
Output (English): no
