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 mYC a metastasis gene for non-small-cell lung cancer?
Answer: Potential markers for detection of metastasis were identified and validated for diagnosis of human biopsies. These markers may represent targets for future therapeutic intervention as they include genes such as Gata4 that are exclusively expressed during lung development.
yes

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: Do increased urinary interleukin 22 binding protein levels correlate with lupus nephritis activity?
Answer: Urinary but not serum IL-22BP levels were associated with active renal disease. Urinary levels of IL-22BP might be a potential marker for the presence of renal involvement in patients with SLE.

yes
