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.

Q: Question: Are findings in the distal colorectum associated with proximal advanced serrated lesions?
Answer: The findings at flexible sigmoidoscopy that traditionally serve as indications for colonoscopy (conventional adenomas) are likely to be ineffective for detection of proximal ASL. This finding, plus the observation that most patients with proximal ASL have no distal polyps, favors screening colonoscopy over sigmoidoscopy, especially in the elderly. The observation that non-advanced distal SSA/Ps are associated with any proximal SSA/P warrants further study.

Q: 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.

A: no

Q: Question: Does chronic competitive flow from a patent arterial or venous graft to the circumflex system impair the long-term patency of internal thoracic artery to left anterior descending grafts in patients with isolated predivisional left main disease : long-term angiographic results of 2 different revascularization strategies?
Answer: In patients with IOSLM, long-term ITA to left anterior descending artery patency is not jeopardized by chronic flow competition from a concomitant arterial or venous graft to the circumflex system. Notably, the addition of a second ITA graft or of a SV to the first ITA does not lead to differences in long-term angiographic patency. Our results minimize the role of flow competition in this setting and should be kept in mind when choosing the appropriate graft configuration.

A:
no
