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: 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.
[A]: yes


[Q]: Question: Does mechanical ventilation with lower tidal volumes influence the prescription of opioids or sedatives?
Answer: Concerns regarding sedation requirements with use of lower V(T) are unfounded and should not preclude its use in patients with ALI/ARDS.
[A]: no


[Q]: Question: Does neutralization of vascular endothelial growth factor slow progression of retinal nonperfusion in patients with diabetic macular edema?
Answer: Just as high VEGF levels contribute to progression of retinal nonperfusion in retinal vein occlusion, the same is true in patients with DME, suggesting that regardless of the underlying disease process, high levels of VEGF can cause closure of retinal vessels. However, our data also suggest that VEGF-induced worsening of retinal perfusion in DME is superimposed on another cause of more gradually worsening perfusion, possibly glucotoxicity. Thus, monthly injections of ranibizumab can slow, but not completely prevent, retinal capillary closure in patients with DME.
[A]:
yes
