Attrition is the term that describes a situation in which participants drop out of a longitudinal study. This can lead to biased results if those who drop out are different from those who continue to participate. Selective survival and cohort effect refer to different phenomena, while selective sampling refers to a bias in the selection of participants at the start of a study.
