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.

Q: Question: Is low caregiver health literacy associated with higher pediatric emergency department use and nonurgent visits?
Answer: Over half of caregivers presenting with their children to the ED have low health literacy. Low caregiver health literacy is an independent predictor of higher ED use and use of the ED for nonurgent conditions. In children without a chronic illness, low health literate caregivers had more than 3 times greater odds of presenting for a nonurgent condition than those with adequate health literacy.

A: yes

Q: Question: Does expression microarray identify the unliganded glucocorticoid receptor as a regulator of gene expression in mammary epithelial cells?
Answer: This work presents the first identification of targets of unliganded GR. We propose that the balance between targets of liganded and unliganded GR signaling is responsible for controlling differentiation and apoptosis, respectively, and suggest that gene regulation by unliganded GR may represent a mechanism for reducing the risk of breast tumourigenesis by the elimination of abnormal cells.

A: yes

Q: Question: Does a unique protein profile of peripheral neutrophils from COPD patients reflect cytokine-induced protein profiles of neutrophils in vitro?
Answer: These results show that neutrophils from COPD patients have a unique protein profile compared to neutrophils from healthy age-matched controls. Furthermore, the neutrophil profiles of COPD patients do not reflect putative dominant signals induced by TNFα, GM-CSF or their combination. Our results indicate that systemic neutrophil responses in COPD patients are caused by a unique but subtle interplay between multiple inflammatory signals.

A:
no
