目的简述“率”的标化和“率”的校正的概念、区别以及计算方法,并用SAS宏程序实现直接标化率、间接标化率以及校正的率的计算,并以统计表格形式直接输出到rtf文件中。方法对直接标化率、间接标化率以及校正的率的计算过程编写通用的SAS宏程序。结果整理好相应的原始数据,设定好相应的宏参数,运行宏程序便可快速获得直接标化率、间接标化率以及校正的率的计算结果。结论笔者编写的直接标化率、间接标化率以及校正的率的SAS宏程序具有通用、简便、实用的特点,在流行病学研究中具有一定的实用价值。
The purpose of this paper is to summarize the concepts, differences and calculation methods of the calibration of “rate ” and “rate ”, and the calculation of direct normalization rate, indirect normalization rate and correction rate using SAS macro program, Statistics form directly output to rtf file. Methods General SAS macros are prepared for the calculation of direct standardization rate, indirect standardization rate and correction rate. Result The corresponding raw data is sorted out, the corresponding macro parameters are set, and the results of direct normalization rate, indirect normalization rate and corrected rate can be quickly obtained by running the macro program. Conclusions The SAS macro programs written by the author in terms of direct standardization rate, indirect standardization rate and correction rate are universal, simple and practical, and have certain practical value in epidemiological studies.
