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 apoptosis inhibitor-5 overexpression associated with tumor progression and poor prognosis in patients with cervical cancer?
Answer: API5 expression is associated with pERK1/2 in a subset of cervical cancer patients and its expression predicts poor overall survival, supporting that API5 may be a promising novel target for therapeutic interventions.
yes

Question: Is patient satisfaction biased by renovations to the interior of a primary care office : a pretest-posttest assessment?
Answer: Renovating the interior of a primary care office was associated with improved patient satisfaction, including satisfaction in domains otherwise unchanged. Physician skills and patient satisfaction sometimes depend on surrounding factors that may bias the ability of patients to assess the quality of medical care. These biases should be taken into account when quality assessment instruments are designed for patients.
yes

Question: Does epoetin requirement depend on dialysis dose when Kt/N > 1.33 in patients on regular dialysis treatment with cellulosic membranes and adequate iron stores?
Answer: In iron-replete HD patients on cellulosic membranes and stabilized epoetin therapy, inadequate dialysis was associated with higher epoetin requirement, but for Kt/V values > or = 1.33, there was no further effect on epoetin responsiveness.
no
