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.
question:
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.
answer:
no


question:
Question: Is neutrophil-lymphocyte ratio a reliable predictive marker for early-stage diabetic nephropathy?
Answer: Increased NLR was significantly associated with DN, and high NLR values may be a reliable predictive marker of early-stage DN.
answer:
yes


question:
Question: Are high levels of serum mannose-binding lectins associated with the severity and clinical outcomes of severe traumatic brain injury?
Answer: Increased serum level of MBL was independently associated with head trauma severity and long-term clinical outcomes of STBI.
answer:

yes
