Example Input: Question: Does clinical evaluation of pazopanib eye drop versus ranibizumab intravitreal injections in subjects with neovascular age-related macular degeneration?
Answer: Pazopanib was well tolerated. Daily pazopanib eye drops in neovascular AMD subjects did not result in therapeutic benefit beyond that obtained with ranibizumab alone.
Example Output: yes

Example Input: Question: Does fibroblast growth factor 8 regulate postnatal development of paraventricular nucleus neuroendocrine cells?
Answer: First, Fgf8 hypomorphy did not eliminate VP and CRH neurons in the mouse PVN, but rather disrupted the postnatal timing of neuropeptide expression onset in PVN neurons. Second, Fgf8 hypomorphy may, in part, be an explanation for affective disorders involving hyperactivity of the HPA axis, such as anxiety.
Example Output: yes

Example Input: Question: Does preoperative haemostasis testing predict requirement of blood products in cardiac surgery?
