根据基于人群的心血管疾病调查的数据确定应答偏倚对比值比结果的影响。研究对象包括一个以白色为主的中上阶层社区的5000名成年居民。1100名非受访者中有60%的信息是通过电话获得的。一个简单的误差项被开发来转换的比值比的受访者为目标人群的比值比使用单个细胞的反应率。这个误差项表明，发现的响应模式往往会使受访者的比值比计算误差最小化。只有通过获得非应答者的相关信息，研究者才能准确估计应答偏倚及其对比值比的影响。
The effect of response bias on odds ratio results was determined based on data from a population-based cardiovascular disease survey. The study subjects consisted of 5000 adult residents of a predominantly white, upper-middle class community. Information from 60% of the 1100 nonrespondents was obtained by telephone. Consistent patterns of participation associated with risk factors and diseases under study were found. A simple error term was developed to convert the odds ratio for respondents to the odds ratio for the target population using individual cell response rates. This error term demonstrates that the response patterns found tended to minimize the error in odds ratio calculations for respondents. Only by obtaining relevant information on nonrespondents can investigators accurately estimate response bias and its effects on the odds ratio.
