question:
Question: Does gender difference affect the outcomes of eccentric rotational acetabular osteotomy used in hip dysplasia?
Answer: The mean operative time and the blood loss were not significantly different between male and female patients. Postoperative CE angle tended to be smaller in male than female patients. The survival rate was not significantly different between males and females. Gender difference did not affect the clinical outcomes of ERAO in patients with hip dysplasia.
answer:
no

question:
Question: Does monocyte chemoattractant protein-1 or macrophage inflammatory protein-1alpha deficiency affect angiotensin II-induced intimal hyperplasia in carotid artery ligation model?
Answer: These results indicate that MCP-1 or MIP-1alpha may not be essential in mediating the proliferative effects of Ang II, a major pathological changes in intimal hyperplasia in the carotid artery ligation model.

question:
Question: Does femoral angiogram prior to arteriotomy closure device reduce vascular complications in patients undergoing cardiac catheterization?
Answer: We found no evidence that performing an FA prior to ACD placement as recommended by the manufacturer had any influence on the clinical success rate of ACD placement or rates of VCs. Therefore, ACD use without FA guidance in patients undergoing CA/PCI is an equally safe and effective method in successfully obtaining hemostasis without an increased risk of VCs.
answer:
no
