We originally planned to obtain unpublished data from included trials through email correspondence with the first authors of included publications and pharmaceutical companies.
When the reported data are insufficient or ambiguous, two of the authors (Y-EK and HWL) will contact the corresponding authors of the clinical trials by email or telephone to request additional information or clarification.
Although appearing very effective, the TDM for postal questionnaires could be labour-intensive to implement, expensive and may no longer be applicable to some participant groups, for example, young people used to other modes of communication, or in trials using email, text or online data collection.
Although appearing very effective, the total design method for postal questionnaires could be labour intensive to implement, expensive and may no longer be applicable to some participant groups (e.g. young people), or in trials using email, text or the Internet to collect data.
A document explaining the proposal (i.e. to work with multiple research teams to test alternative recruitment approaches across multiple trials) was emailed to participants prior to interview.
"It was a victimless crime, I think, and it was an email trial.
We tried to complement all missing data by correspondence with trial authors (via email).
