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: Does three-dimensional assessment of ultrasound features in women with clomiphene citrate-resistant polycystic ovarian syndrome ( PCOS ) : ovarian stromal volume correlate with biochemical indices?
Answer: These findings demonstrate an association of the total ovarian volume, pre-antral follicle number and total follicular volume with some of the biochemical indices of PCOS, but no association was observed between ovarian stromal volume and these indices.
no

Question: Does increased expression of prostasin contribute to early-onset severe preeclampsia through inhibiting trophoblast invasion?
Answer: These findings suggest that prostasin may suppress the invasion process in preeclampsia by attenuating MMP2 and MMP9 secretion.
yes

Question: Do abnormal arterial blood gas and serum lactate levels alter disposition in adult blunt trauma patients after early computed tomography?
Answer: We found that abnormal ABG / SL results do not change management or discharge disposition in patients without clinical or radiographic evidence of traumatic injury on CT C&A. Among patients who receive CT C&A, the routine measurement of arterial blood gas and lactate may be an unnecessary source of additional cost, patient discomfort, and delay in care.
no
