在一项基于人群的心血管研究中，研究了参与者和非参与者之间心血管健康状况的差异。对非应答者的电话访谈显示心血管疾病普遍较多，但高脂血症和心血管疾病家族史较少。非应答者在已知高血压、饮食或高脂血症药物治疗或鸡蛋使用方面没有差异。没有受访者更有可能是吸烟者。由于本研究中非应答者的偏倚较少，而应答率较高，因此应答者总体上代表了目标人群。然而，如果无反应率和/或基线差异相当大，观察到的差异可能产生虚假的高风险因素患病率估计值，低疾病患病率估计值和偏倚的相对风险。
The differences in cardiovascular health status between participants and non-participants were examined in a population-based cardiovascular study. Telephone interviews with non-respondents revealed generally more cardiovascular disease but less hyperlipidemia and family history of cardiovascular disease. Non-respondents did not differ regarding known hypertension, diet or drug therapy for hyperlipidemia or egg use. None-respondents were more likely to be cigarette smokers. Because the amount of non-respondent bias in the study was small while the response rate was high, respondents were generally representative of the target population. However, the observed differences could have produced spuriously high estimates of risk factor prevalence, low estimates of disease prevalence and biased relative risks if the non-response rate and/or the baseline differences were considerably larger.
