intention to treat analysis

An analysis in which all trial participants are analysed according to the intervention to which they were allocated, whether they received that therapy or not. Such analyses are favoured in assessing effectiveness, as they mirror non-compliance and treatment changes likely to occur when the intervention is used in practice, and because of the risk of attrition bias when participants are excluded from the analysis.
