Many softwares have been adapted for medical use; they rarely enable conveniently both data management and statistics. A recent cooperative work ended up in a new software, Sem (Statistics Epidemiology Medicine), which allows data management of trials and, as well, statistical treatments on them. Very convenient, it can be used by non professional in statistics (biologists, doctors, researchers, data managers), since usually (excepted with multivariate models), the software performs by itself the most adequate test, after what complementary tests can be requested if needed. Sem data base manager (DBM) is not compatible with usual DBM: this constitutes a first protection against loss of privacy. Other shields (passwords, cryptage...) strengthen data security, all the more necessary today since Sem can be run on computers nets. Data organization enables multiplicity: forms can be duplicated by patient. Dates are treated in a special but transparent manner (sorting, date and delay calculations...). Sem communicates with common desktop softwares, often with a simple copy/paste. So, statistics can be easily performed on data stored in external calculation sheets, and slides by pasting graphs with a single mouse click (survival curves...). Already used over fifty places in different hospitals for daily work, this product, combining data management and statistics, appears to be a convenient and innovative solution.
许多软件已被改编用于医学领域；但它们很少能同时方便地进行数据管理和统计分析。最近的一项合作成果是一款新软件Sem（统计流行病学医学软件），它可以对试验数据进行管理，并对这些数据进行统计处理。该软件非常便捷，非统计专业人员（生物学家、医生、研究人员、数据管理员）也能使用，因为通常情况下（多元模型除外），软件会自行执行最合适的测试，如有需要还可要求进行补充测试。Sem数据库管理器（DBM）与常用的DBM不兼容：这是防止隐私泄露的第一道防线。其他防护措施（密码、加密等）加强了数据安全性，如今这一点更加必要，因为Sem可以在计算机网络上运行。数据组织方式具有多样性：表单可以按患者进行复制。日期处理方式特殊但直观（排序、日期和时间间隔计算等）。Sem可以与常见的桌面软件通信，通常只需简单的复制/粘贴操作。因此，可以轻松地对外部计算表中存储的数据进行统计分析，通过单次鼠标点击粘贴图表（生存曲线等）即可生成幻灯片。该产品已在不同医院的五十多个地方用于日常工作，它将数据管理和统计分析相结合，似乎是一个方便且创新的解决方案。
