Survival-related selection bias in studies of racial health disparities: the importance of the target population and study design

Jun 29, 2020

Two approaches could be used to minimize the survival-related selection bias: 1. change the target population or 2. change the study design. Studies of racial health disparities may be subject to selection bias due to the exclusion of persons who die subsequent to conception or birth before the outcome of interest occurs or can be assessed in the study.  If the potential for selection bias exists, changing the target population or study design may lessen the possibility of such selection bias. However, findings from the new target population or study design may apply to fewer people or may be more subject to other biases (e.g., measurement).Therefore, the advantages of altering the target population or study design should be weighed against the disadvantages.
