The authors carried out a critical assessment of the literature to learn about the extent of use of the case-control method in outbreak investigations, and to identify problems observed in the use of this method to investigate outbreaks. The literature search comprised reports of outbreak investigations from the MEDLINE system, Morbidity and Mortality Weekly Report, and six epidemiologic and medical journals. The proportion of these reports that used the case-control method increased from one article out of 519 in the 1960-1965 period to 144 out of 845 reported outbreaks in the 1980-1985 period. A comparison of the case-control studies of outbreak investigations in the 1970-1975 period with those in the 1980-1985 period revealed relatively more sophisticated methods of analysis in the latter period.
作者对文献进行了批判性评估，以了解病例对照法在疫情调查中的使用程度，并确定在使用该方法调查疫情时所观察到的问题。文献检索包括来自MEDLINE系统、《发病率与死亡率周报》以及六种流行病学和医学期刊的疫情调查报告。这些报告中使用病例对照法的比例从1960 - 1965年期间519篇文章中的1篇增加到1980 - 1985年期间报告的845起疫情中的144篇。将1970 - 1975年期间疫情调查的病例对照研究与1980 - 1985年期间的进行比较发现，后期的分析方法相对更复杂。
