在疾病的监测和防治工作实践中,人们越来越多地遇到有关率的计算、标准化和标化率的统计学检验的问题。本文介绍一种较简便的标化率的统计学检验方法。方法从原始数据计算出的率(如发病率、死亡率、患病率)为粗率。样本人群的某些与疾病有关的特征往往影响粗率的结果,其中最典型 In the practice of disease surveillance and prevention and control, people are increasingly confronted with problems related to the calculation of the rate, the standardization and the statistical test of standardized rates. This article introduces a simple statistical test method for standardized rates. Methods The rates calculated from the raw data (eg, morbidity, mortality, prevalence) were rough. Some of the disease-related features of the sample population tend to affect rough results, the most typical of which
