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: Does an ultrasound-guided fascia iliaca catheter technique impair ambulatory ability within a clinical pathway for total hip arthroplasty?
Answer: BMI affects postoperative ambulation outcome after hip arthroplasty, whereas the type of regional analgesic technique used does not. An ultrasound-guided FIC technique offers similar analgesia with fewer side effects when compared with ITM.
[A]: no


[Q]: Question: Does a common variant in the precursor miR-146a sequence predispose to cholangiocarcinoma in a large European cohort?
Answer: Our data do not support a prominent contribution of the pre-miR-146a sequence variant in the genetic predisposition to CCA. However, current studies functionally characterizing rs2910164 have proposed that distinct repertoires of target genes are addressed by genotype-specific mature miR-146a species. Given the detected trend towards a potentially protective role of GC heterozygosity, a subtle modulation of genetic CCA risk by the pre-miR-146a GC genotype may exist and should be evaluated further.
[A]: no


[Q]: Question: Does prolonged stenting prevent obstruction after TIP repair when the glans was deeply incised?
Answer: Our data indicate that prolonged stenting does not give better results in those TIP repairs, in whom the urethral plate was incised across the rim of the neomeatus. The early excellent aspect of the glans after stent removal is often impaired by partial closure of the glans incision with a short-term change in size and position of the meatus. To prevent this, the rim of the meatus during reconstruction should be kept completely epithelialised.
[A]:
no
