Preferred Label : Missing Data;
NCIt definition : Required or expected data that is not present, which may be due to non-completion
or corruption.;
Alternative definition : CDISC-GLOSS: Data not completed or corrupted in reports and case report forms, e.g.,
the data not captured when a subject withdraws from a trial. NOTE: Reviewers are concerned
about missing data since patients who are not improved or who believe they have experienced
side effects may be particularly prone to leave a trial, thus skewing the analysis
of results if such analysis were to be done only on the subjects who had continued
with the trial. Trial designs therefore specify plans for how such missing data will
be treated in analysis. See also intention to treat. [FDA Guidance on Subject Withdrawal,
2008];
