To make a contribution to a base of knowledge, research design must be sound and the data must be analyzed by the most efficient, powerful method available. In conducting orthopaedic research as well as when interpreting the orthopaedic literature, knowledge of multivariable analysis is essential in evaluating the effects of variables that may confound or influence the relationship of interest. An understanding of the basic tenets, underlying assumptions, and purposes of frequently used types of multivariable analysis is necessary for an accurate, critical evaluation of a study's results.
为了对知识基础有所贡献，研究设计必须合理，并且数据必须采用现有最有效、最强大的方法进行分析。在开展骨科研究以及解读骨科文献时，多变量分析知识对于评估可能混淆或影响感兴趣关系的变量的作用至关重要。对于准确、批判性地评估研究结果而言，了解常用多变量分析类型的基本原理、潜在假设和目的是必要的。
