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.

[EX Q]: Question: Do post-ERCP pancreatitis rates differ between needle-knife and pull-type pancreatic sphincterotomy techniques : a multiendoscopist 13-year experience?
Answer: The risk of post-ERCP pancreatitis does not differ between EPS techniques when performed at a high-volume pancreaticobiliary referral center when using routine prophylactic pancreatic duct stent placement.
[EX A]: no

[EX Q]: Question: Does extended pattern prostate biopsy minimize the volume-grade bias in prostate cancer detection?
Answer: Although more high grade cancers are detected with extended pattern biopsy, there is no differential upgrading with respect to prostate volume. Based on these observations extended prostate sampling in trials of agents that decrease prostate volume would have minimal impact on volume-grade associations.
[EX A]: no

[EX Q]: Question: Does short-term soy and probiotic supplementation markedly affect concentrations of reproductive hormones in postmenopausal women with and without histories of breast cancer?
Answer: These data suggest that short-term, moderate consumption of isoflavone-containing soy protein and consumption of these particular probiotic capsules do not significantly alter reproductive hormone concentrations in breast cancer survivors or controls, regardless of equol producer status.
[EX A]:
no
