| Abstract: |
| Meta—analysis是对先前研究资料进行合并分析的一种新的研究方法,其原理简单、系统,结果全面、量化,可靠性好,为流行病学研究提供了一种强有力的统计分析手段。本文介绍了这种方法的基本原理,讨论了它在流行病学应用中的一些问题,试用于极低频电磁场与儿童白血病关系的研究,结果表明儿童白血病的发生与极低频电磁场暴露有关。 |
| English Abstract: |
| Meta-analysis provides a powerful statistical tool for epidemiological study. The basic principle of meta-analysis is introduced in thispaper, and some problems about its application in epidemiology are discussed. This method was used by the authors to study the relationship between exposure to extreme low frequency electromagnetic fields (ELF) and childhood leukemia, and the result showed that there is a significant association between them. |
