在检验准确性的研究中，如果只有部分受检者接受疾病验证，则会出现验证偏倚。目前用于校正验证偏倚的方法假设验证具有条件独立性，这意味着验证患者的概率仅取决于测试结果，而不取决于患者未观察到的疾病状态。
Verification bias can occur in studies of test's accuracy if only some of tested patients receive disease verification. The current methods for correcting for verification bias assume conditional independence for verification, which means that the probability of verifying a patient depends only on the test result, not on the unobserved disease status of the patient.
