0 gradually making something weaker and destroying it, especially the strength or confidence of an enemy by repeatedly attacking it:
1 a gradual reduction in the number of people who work for an organization that is achieved by not replacing those who leave:
2 a reduction in the number of employees in a company made by not replacing those who leave, rather than forcing people to leave their jobs:
3 a reduction in the number of people who buy a product or service, for example because of its age, increased competition, etc.:
Second, the high rate of follow-up participation reduces the risk of bias due to selective attrition.
Attrition was not an end in itself, but a means to an end.
It is possible that these decreasing scores are due to performance issues, rather than an attrition of underlying competence or knowledge.
The reason for the attrition (death/other) was not significantly associated with age.
Inconclusive studies covered diverse interventions and were characterised by poor reporting, weak study design, high attrition rates, and small or unrepresentative samples.
There were no significant differences in attrition rates at sixth and eighth grades related to peer status or aggression at third grade.
Each group of mice was assayed for early phase attrition by skin or skin and lung recovery; and for late phase attrition by liver perfusion.
Furthermore, comparison of participants and the eligible population show that sample attrition is an unlikely source of confounding in this investigation.
