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 detection of molecular bacterascites in decompensated cirrhosis define a risk with decreased survival?
Answer: BactDNA quantification in ascitic fluid samples using culture-independent 16S rRNA gene-based methods seems to be an interesting approach to identify patients at risk of reduced survival. Our study warrants further evaluation of antibiotic treatment in patients with molecular bacterascites.
yes

Question: Does nitric acid passivation affect in vitro biocompatibility of titanium?
Answer: Although the protocol for passivation used here could interfere with the pattern of ions released from Ti-6Al-4V and cpTi surfaces, the present study did not show any effect of this surface treatment on in vitro biocompatibility of Ti as evaluated by osteoblast attachment, proliferation, and differentiation.
no

Question: Does rofecoxib appear to increase the risk of venous thromboembolism : a systematic review of the literature?
Answer: Our findings are limited by the relatively small number of events, although, the contributing sample size of 28307 subjects (18309 person years) is reasonable. From our best available data outlined in this manuscript, there is no increase in the risk of VTE with rofecoxib use.

no
