流行病学病例对照研究中经常使用随机数字拨号来选择基于人群的对照，即使病例和对照都是面对面访谈的。然而，人们仍然担心随机数字拨号的潜在偏差，特别是考虑到其响应率普遍较低。在佐治亚州亚特兰大的一项乳腺癌病例对照研究中，对 20-54 岁女性进行了面对面访谈，对两个统计上独立的对照组进行了比较：通过随机数字拨号获得的对照组 (n = 652) 和通过面积概率抽样获得的对照组 (n = 640)。该地区样本的家庭筛查率明显较高，达 5.5%。访谈回复率相当。电话样本估计，没有符合年龄条件的女性的家庭比例要大得多（约 7%）。两个对照组（经过适当加权）都具有与美国人口普查亚特兰大女性人口特征相似的特征，不同之处在于两个对照组的受访者受教育程度更高，结婚的可能性更大。作者得出的结论是，通过随机数字拨号联系的家庭参与家庭筛选过程的可能性较小，如果他们合作，一些家庭可能不会透露符合年龄条件的妇女居住在其中。研究人员需要开发改进的方法，在针对特定亚人群（例如女性）的随机数字拨号调查中筛选和计数家庭成员。
Random digit dialing is used frequently in epidemiologic case-control studies to select population-based controls, even when both cases and controls are interviewed face-to-face. However, concerns persist about the potential biases of random digit dialing, particularly given its generally lower response rates. In an Atlanta, Georgia, case-control study of breast cancer among women aged 20-54 years, all of whom were interviewed face-to-face, two statistically independent control groups were compared: those obtained through random digit dialing (n = 652) and those obtained through area probability sampling (n = 640). The household screening rate was significantly higher for the area sample, by 5.5%. interview response rates were comparable. The telephone sample estimated a significantly larger percentage (by approximately 7%) of households to have no age-eligible women. Both control groups, appropriately weighted, had characteristics similar to US Census demographic characteristics for Atlanta women, except that respondents in both control groups were more educated and more likely to be married. The authors conclude that households contacted through random digit dialing are somewhat less likely to participate in the household screening process, and if they are cooperative, some households may not disclose that age-eligible women reside therein. Investigators need to develop improved methods for screening and enumerating household members in random digit dialing surveys that target a specific subpopulation, such as women.
