Effects of attrition. Attrition can introduce bias if the characteristics of people lost to follow-up differ between the randomised groups. In terms of bias, this loss is important only if the differing characteristic is correlated with the trial's outcome measures. Longitudinal studies are important in public health research for identifying risk factors related to negative health outcomes. However, a major concern in such studies is that the longer the follow-up period, the higher the chances are for drop-out [1]. Attrition rates from 30 to 70% are often reported [2-7]. Article Summary Your company’s attrition rate is the rate at which employees voluntarily leave your firm. The attrition rate is also referred to as the employee turnover rate or the “churn” rate.
