Dealing with missing data
An intention-to-treat analysis (ITT) is one in which all the participants
in a trial are analysed according to the intervention to
which they were allocated, whether they received the intervention
or not. For each trial we planned to report whether or not the
investigators stated if the analysis was performed according to the
ITT principle. If participants were excluded after allocation, we
reported any details that were provided in full.
