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: Is vitamin D deficiency in septic patients at ICU admission a mortality predictor?
Answer: In our cohort, septic patients showed a significantly lower vitamin D level than trauma patients in comparison to age cohort patients with the same demographic/clinical characteristics, but no clear relationship between vitamin D level and outcome was found. Further studies with larger samples are needed to clarify the prognostic role of vitamin D and nutraceutical interventions in critically ill patients.

Output: no


Input: Consider Input: Question: Is microvasculopathy observed in early or late endomyocardial biopsies related to angiographically confirmed transplanted heart coronary vasculopathy?
Answer: Microvasculopathy observed early or late after OHT was not related to angiographically confirmed CAV.

Output: no


Input: Consider Input: Question: Does hydrogen sulfide inhibit MPP ( + ) -induced apoptosis in PC12 cells?
Answer: H2S significantly protected PC12 cells against cytotoxicity and apoptosis induced by MPP(+), which was associated with the inhibition by H(2)S of MPP(+)-induced dissipation of MMP and overproduction of ROS. These findings can significantly advance therapeutic approaches to the neurodegenerative diseases which are associated with oxidative stress, such as Parkinson's disease.


Output: yes
