Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.

Input: Consider Input: Question: Does early removal of central venous catheter in patients with candidemia improve outcome : analysis of 842 patients from 2 randomized clinical trials?
Answer: In this cohort of 842 adults with candidemia followed up prospectively, early CVC removal was not associated with any clinical benefit. These findings suggest an evidence-based re-evaluation of current treatment recommendations.

Output: no


Input: Consider Input: Question: Is race a predictor of prostate cancer detection on repeat prostate biopsy?
Answer: Race is not a predictor of prostate cancer detection in men undergoing repeat prostate biopsies. With the exception of HGPIN, all other clinical parameters were similar between black and white men. Serum PSA, PSA velocity, HGPIN and ASAP were found to be significant predictors of subsequent prostate cancer detection.

Output: no


Input: Consider Input: Question: Do changes in middle cerebral artery velocity after carotid endarterectomy identify patients at high-risk of suffering intracranial haemorrhage or stroke due to hyperperfusion syndrome?
Answer: We were unable to demonstrate that significant increases in MCAV and PI were able to predict patients at increased risk of suffering a post-operative stroke due to HS or ICH. The provision of written guidance for managing PEH in Group 2 patients was associated with virtual abolition of ICH/HS.


Output: no
