In this series on research study designs, we have so far looked at different types of primary research designs which attempt to answer a specific question. In this segment, we discuss systematic review, which is a study design used to summarize the results of several primary research studies. Systematic reviews often also use meta-analysis, which is a statistical tool to mathematically collate the results of various research studies to obtain a pooled estimate of treatment effect; this will be discussed in the next article.
在这个关于研究设计的系列文章中，到目前为止我们已经探讨了旨在回答特定问题的不同类型的原始研究设计。在这一部分，我们将讨论系统评价，它是一种用于总结多项原始研究结果的研究设计。系统评价通常还会使用荟萃分析，这是一种统计工具，用于对各项研究的结果进行数学汇总，以获得治疗效果的合并估计值；这将在下一篇文章中讨论。
