A method for estimating the size of the group necessary in evaluation of the efficacy of preventive intervention among the population is described. The parameters for calculating the necessary size of the sample from an equation and the fundamentals of compiling tables by means of electronic computers are discussed. The data of the Kaunas survey conducted according to the WHO program illustrate the statistical approach. The material of the Kaunas survey is also used to estimate the size of the population necessary for testing the hypothesis on the possibility of preventing myocardial infarction by reducing the risk factor.
本文描述了一种估算在人群中评估预防性干预效果所需样本量的方法。讨论了从一个方程计算所需样本量的参数以及借助电子计算机编制表格的基本原理。根据世界卫生组织计划进行的考纳斯调查数据说明了这种统计方法。考纳斯调查的材料还用于估算为检验通过降低危险因素预防心肌梗死可能性的假设所需的人群规模。
