临床医学研究数据分类浅谈

The classification and transformation of data in clinical research

数据统计分析是临床医学研究中的一个重要组成部分。在临床研究实践中,有些研究结果存在统计分析错误或不规范的现象,主要系由医务人员对临床研究数据分类认识不足、选用的统计分析方法不恰当所致。本文从认识临床研究数据分类的重要性入手,就临床研究数据分类以及不同分类数据的相互变换方法和原则等作一简要介绍,为医务人员规范开展临床研究提供参考。

Statistical analysis of data is an integral part of clinical medical research.In clinical research practice,some research results have statistical analysis errors or irregularities,which are mainly caused by the insufficient understanding of medical staff to the classification of clinical research data and the selection of inappropriate statistical analysis methods.Starting with understanding the importance of clinical research data classification,the classification of clinical research data and the methods and principles of mutual transformation of different classified data are briefly introduced in this article so as to provide reference for medical personnel to carry out clinical research in a standardized manner.
