**课程名称：** 牙科元分析 - 基础课程 **课程概述：** 本课程将带您了解元分析的概念及其各种图形表示方法。元分析是用于综合来自科学研究的定量结果数据的重要统计工具。研究的选取是在对特定研究问题进行系统性回顾后进行的。本课程解释了元分析常用的不同类型数据，并描述了它们的合并估计值的推导过程。这些合并估计值能告知科学界各种治疗或干预措施的益处或冗余性。课程内容以通俗易懂的语言进行讲解，并结合口腔文献中的良好示例，帮助您更好地理解。 元分析中的另一个重要方面是异质性的存在。异质性是指纳入元分析的研究以及其结局数据中的差异。这种差异可能由多种原因引起，并影响元分析合并估计值的可靠性和有效性。理解异质性及其对结果的影响至关重要。课程还介绍了森林图和漏斗图，它们是数据的图形表示，能清晰地揭示影响结果的各种因素。这些图表是一种散点图，需要与合并估计值的单一测量值一起解读。 加入本课程，提升您在牙科元分析的理解和解读能力。
This course takes you through the concepts of meta-analysis and the various graphical representations. Meta-analysis is an important statistical tool for the synthesis of quantitative data on outcomes derived from scientific studies. The studies are selected following the conduct of a systematic review related to a specific research question. This course explains the different types of data commonly used for meta-analysis and describes the derivation of their pooled estimates. The pooled estimates inform the scientific community of the benefits or redundancy of any treatments or interventions. The content is discussed in simple language with good examples derived from dental literature for you to understand better.The other important aspect when meta-analysis is done is the presence of heterogeneity. These are variations among the selected studies, the outcome data of which are included in the meta-analysis. The variation can occur due to a lot of reasons that can affect the reliability and validity of the meta-analysis pooled estimates. Understanding heterogeneity and how to interpret it effect on the results is important. The course further deals with forest and funnel plots which are graphical presentations of data and give a very clear understanding on the various factors affecting the results. These plots are a form of scatter plot and need to be interpreted along with the single measures of pooled estimates.Come join this course and take yourself to the next level in understanding and interpreting meta-analysis in dentistry.
