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: Is assessment of joint space narrowing with conventional standing antero-posterior radiographs : relief in mild-to-moderate pain a confounder in recent osteoarthritis structure-modifying drug trials?
Answer: Knee pain relief did not bias the report of a structure-modifying effect of glucosamine sulfate in two recent long-term trials, possibly due to the mild-to-moderate patient characteristics. Consensus deliverables should acknowledge that the potential limitations of conventional standing antero-posterior radiographs should not be overestimated since they may not apply to all patient populations and to all studies using this gold standard technique.
no

Question: Does indoleamine 2,3-dioxygenase inhibition alter the non-coding RNA transcriptome following renal ischemia-reperfusion injury?
Answer: These results suggest a biologic role for non-coding, IDO-dependent genes in regulating the early response to IRI.
yes

Question: Are interleukin-1B and interleukin-1 receptor antagonist gene polymorphisms associated with premalignant gastric conditions : a combined haplotype analysis?
Answer: The determination of these IL1-related loci does not have any predictive value for stratification of subgroups with respect to gastric cancer risk.
no
