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.

Input: Consider Input: Question: Are endogenous sex hormones associated with subclinical atherosclerosis in menopausal women?
Answer: Estradiol and testosterone are not associated with subclinical atherosclerosis in menopausal women. A positive correlation between IMT and FSH may reflect an association between low estrogen and IMT. Abdominal fat can be an important link between androgenic levels and cardiovascular risk.

Output: no


Input: Consider Input: Question: Is the G-308A variant of the Tumor Necrosis Factor-alpha ( TNF-alpha ) gene associated with obesity , insulin resistance and body fat distribution?
Answer: Our study did not detect any significant association of the G-308A TNFalpha polymorphism with obesity or with its clinical and metabolic abnormalities in this population. Our data suggests that, in our population, the G-308A TNFalpha polymorphism is unlikely to play a major role in the pathogenesis of these conditions.

Output: no


Input: Consider Input: Question: Are arterial blood gas derangement and level of comorbidity predictors of long-term mortality of COPD patients treated with mechanical ventilation?
Answer: Chronic obstructive pulmonary disease patients treated with invasive mechanical ventilation have substantial long-term mortality. Neither the levels of arterial blood gas values measured immediately before invasive mechanical ventilation was initiated nor the burden of comorbidity were strong determinants of long-term mortality among these patients.


Output: no
