尽管随机数字拨号（RDD）是病例对照研究中控制人群抽样的公认和常用方法，但令人惊讶的是，很少有人尝试将RDD的准确性与最佳传统替代方法进行比较，即，家庭面积调查。本研究的目的是比较各种特征的控制对象选择的ROD和区域调查方法。所有数据都是通过对两种类型的对照组进行面对面访谈收集的。这项地区调查确定了1978年和1979年华盛顿州两个县20至79岁居民的人口样本。膀胱癌、妇科癌症和多发性骨髓瘤的三项病例对照研究的对照组来自该地区样本，共240名对照受试者。在同一时间段内，使用ROD电话抽样确定了来自相同县的21-64岁的对照组用于国家膀胱癌研究。ADD对照组有134名受访者。总体而言，通过这两种不同方法选择的两个对照组产生了各种人群特征的相似估计频率。在某些年龄/性别亚组中观察到的微小差异以及与职业接触有机物质相关的总体测量的统计学意义可能归因于多重比较。
Although random digit dialing (RDD) is an accepted and commonly used method of sampling populations for controls in case-control studies, there have been surprisingly few attempts to compare the accuracy of RDD with that of the best traditional alternative, i.e., household area surveys. The aim of the present study was to compare a variety of characteristics of control subjects selected by ROD and area survey methods. All data were gathered through in-person interviews of both types of control subjects. The area survey identified a population-based sample of 20- to 79-year-old residents of two Washington State counties in 1978 and 1979. Control groups for three case-control studies of bladder cancer, gynecologic cancers, and multiple myeloma were drawn from this area sample, for a total of 240 control subjects. Controls aged 21-64 years from the same counties were identified for the National Bladder Cancer Study using ROD telephone sampling during the same time period. There were 134 respondents in the ADD control group. Overall, the two control groups selected by these two different methods yielded similar estimated frequencies of various population characteristics. The small differences observed in some age/sex subgroups and the statistical significance of the overall measure of association for occupational exposure to organic substances may be attributed to multiple compar isons.
