Task: Answer Verification
Input (English): Question: Are homocysteine and C-reactive protein markers of cognitive impairment in patients with major cardiovascular disease?
Answer: PreCI and POCD are present in a substantial proportion of patients undergoing CABG surgery but there is no independent association with either baseline homocysteine or CRP levels. It is possible that cognitive impairment may result from the vascular disease rather than a direct association with either homocysteine or CRP.
Output (English): no
