The computation of standardized incidence/mortality ratios or Poisson regression requires the calculation of person-years generated in a cohort. Softwares can do that, but SAS users still need to program this step themselves. Various algorithms were published previously, but they do not perform exact calculations: the present paper describes a simple program, which creates exact person-years, and computes SMRs. This program provides a referenced tool to perform this analysis in a cohort, with SAS or another language (the algorithm used can be easily adapted).
标准化发病率/死亡率比的计算或泊松回归需要计算队列中产生的人年数。软件可以做到这一点，但SAS用户仍需自己编写这一步骤的程序。以前已经发表了各种算法，但它们不能进行精确计算：本文描述了一个简单的程序，它可以创建精确的人年数并计算标准化死亡比。该程序提供了一个参考工具，可使用SAS或其他语言在队列中进行此分析（所使用的算法可以轻松改编）。
