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 race a predictor of prostate cancer detection on repeat prostate biopsy?
Answer: Race is not a predictor of prostate cancer detection in men undergoing repeat prostate biopsies. With the exception of HGPIN, all other clinical parameters were similar between black and white men. Serum PSA, PSA velocity, HGPIN and ASAP were found to be significant predictors of subsequent prostate cancer detection.
[A]: no


[Q]: Question: Does a cytotoxic phenotype predict clinical outcome in anaplastic large cell lymphomas?

[A]: no


[Q]: Question: Do peak oxygen uptake during the incremental shuttle walk test in a predominantly female population with Chagas heart disease?
Answer: This study showed the good correlation between distance walked in ISWT and VO2 peak directly measured in both tests, and additionally, provided an equation to calculate a predictive VO2 peak by ISWT, suggesting a good alternative to evaluate the FC of CHD patients, especially in locations where sophisticated testing is not available.
[A]:
yes
