尽管市面上有许多商业可用的统计软件包,但只有少数能进行竞争风险分析或含时间依赖协变量的比例风险回归模型,而这些在造血干细胞移植研究中是必需的。此外,大多数软件包对临床医生不友好,因为它们要求基于统计语言编写命令。本报告介绍了统计软件“EZR”(简易R),它基于R和R commander。EZR能够通过点击操作应用临床研究中经常使用的统计功能,比如生存分析(包括竞争风险分析和时间依赖协变量的使用)、受试者工作特征分析、荟萃分析、样本量计算等等。EZR可在我们的网站(http://www.jichi.ac.jp/saitama - sct/SaitamaHP.files/statmed.html)上免费获取,并且可在Windows(美国微软公司)和Mac OS X(美国苹果公司)系统上运行。本报告提供了EZR的安装和操作说明。
Although there are many commercially available statistical software packages, only a few implement a competing risk analysis or a proportional hazards regression model with time-dependent covariates, which are necessary in studies on hematopoietic SCT. In addition, most packages are not clinician friendly, as they require that commands be written based on statistical languages. This report describes the statistical software ‘EZR' (Easy R), which is based on R and R commander. EZR enables the application of statistical functions that are frequently used in clinical studies, such as survival analyses, including competing risk analyses and the use of time-dependent covariates, receiver operating characteristics analyses, meta-analyses, sample size calculation and so on, by point-and-click access. EZR is freely available on our website (http://www.jichi.ac.jp/saitama-sct/SaitamaHP.files/statmed.html) and runs on both Windows (Microsoft Corporation, USA) and Mac OS X (Apple, USA). This report provides instructions for the installation and operation of EZR.
