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 nonadherence with ambulatory saliva sampling associated with biased salivary testosterone estimates?
Answer: The results suggest that common ambulatory nonadherence with scheduled saliva sampling is associated with biased salivary testosterone estimates. They will inform further studies estimating salivary testosterone with ambulatory saliva-sampling designs and highlight the relevance of strategies to improve or confirm adherence, beyond routinely used instructions.
yes

Question: Does neo/adjuvant chemotherapy improve outcome in resected primary synovial sarcoma : a study of the French Sarcoma Group?
Answer: As for other high-grade soft-tissue sarcomas, well-planned wide surgical excision with adjuvant radiotherapy remains the cornerstone of treatment for SS. Neo-adjuvant or adjuvant chemotherapy should not be delivered outside a clinical trial setting.
no

Question: Is myocardial scar characteristics based on cardiac magnetic resonance imaging associated with ventricular tachyarrhythmia in patients with ischemic cardiomyopathy?
Answer: A relatively large peri-infarction mass is associated with sustained VT and/or appropriate ICD therapy, whereas age and lower LVEF are associated with mortality. CMR based tissue characterization could aid in the prediction of specific outcome measures and in clinical decision making.

yes
