Intention-to-Treat (ITT) Analysis: This method includes all participants in the groups to which they were originally assigned, regardless of dropout.
Imputation Techniques: Methods such as multiple imputation can estimate missing data.
Sensitivity Analysis: This involves testing how results change with different assumptions about the missing data.
