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: Does lung-protective mechanical ventilation protect against acute kidney injury in patients without lung injury at onset of mechanical ventilation?
Answer: In the present study in critically patients without ALI at onset of mechanical ventilation, lower tidal volume ventilation did not reduce the development or worsening of AKI compared with conventional tidal volume ventilation.
no

Question: Does chronic reduction of myocardial ischemia attenuate coronary collateral development in miniswine?
Answer: We conclude that growth and development of the coronary collateral circulation measured functionally during exercise at 90% of maximal heart rate is unrelated to the extent and duration of myocardial ischemia in this model.
no

Question: Do nomograms incorporating serum C-reactive protein effectively predict mortality before and after surgical treatment of renal cell carcinoma?
Answer: We have generated nomograms incorporating serum C-reactive protein levels that effectively predict overall mortality and renal cell carcinoma specific mortality. Our findings warrant external validation.

yes
