Laboratory determinations on children aged 6 to 10 years obtained over a 5-year period are analysed by a method described in detail for differentiating between children from exposed and control areas of Seveso, Italy. In the analysis, stratification is employed to distinguish the separate days of laboratory measurement. The analyses permit the study of differences based on all variables simultaneously as well as on each variable separately. Results are obtained for each individual year and for longer intervals of 2 successive years, 3 successive years, 4 successive years, and all 5 years. The results and some statistical aspects of the analysis are discussed.
采用一种详细描述的方法，对意大利塞韦索暴露区和对照区6至10岁儿童在5年期间进行的实验室检测结果进行分析。在分析中，采用分层法区分实验室测量的不同日期。这些分析允许同时基于所有变量以及分别基于每个变量研究差异。得出了每一年以及连续2年、连续3年、连续4年和全部5年的更长时间段的结果。对结果以及分析的一些统计学方面进行了讨论。
