Sensitivity analyses for each outcome where applicable
SECONDARY
In the primary analysis, missing data will not be imputed. In secondary analyses of the primary outcome and key secondary outcomes, multiple imputation by chained equations (MICE) will be used. For analysis of clustered data it is important that the model for imputation includes cluster-specific random effects [If the effect of the intervention is statistically significant, and remains so in the MICE analysis detailed above then the multiple imputation analysis will also be extended to determine the amount of bias over and above that allowed for by the multiple imputation model that would render the primary analysis non- statistically significant.
