Intent-to-Treat Analysis

An analysis based on the initial treatment intent, not on the treatment eventually administered. For example, if the treatment group has a higher attrition rate than the control or comparison group, and outcomes are compared only for those who completed the treatment, the study results may be biased. An intent-to-treat design ensures that all study participants are followed until the conclusion of the study, irrespective of whether the participant is still receiving or complying with the treatment.
