一、Cochrane协作网及其历史随着现代医学的发展,研究者为了寻找更为安全有效的医疗技术和药品所进行的临床研究不断增加。但是,由于受到各种现实条件的限制,几乎任何一项单独的临床研究的结果都不可能具有百分之百的可靠性。如果能将针对同一医学问题的各项研究结果进行比较和总结,则有利于我们得到更为可靠的结果,以供健康相关部门进行更为科学的决策。这就需要有大量的研究者,收集发生在不同时间、不同地点、不同样本、不同国家进行的各项相关研究的资料,按
First, the Cochrane Collaboration Network and its history With the development of modern medicine, researchers in clinical research to find more secure and effective medical technology and medicines are increasing. However, due to various realistic conditions, the results of almost any single clinical study are unlikely to be 100% reliable. If we can compare and summarize the results of the research on the same medical problem, then it will help us to get more reliable results for health-related departments to make more scientific decisions. This requires a large number of researchers to collect information on various studies that take place at different times, in different locations, in different samples and in different countries.
