Meta-analysis of clinical trials: Summary of an international conference
- 61 Downloads
An international conference of clinicians, clinical investigators and biostatisticians discussed meta-analysis in relation to clinical trials, i.e. the combination of data from separate studies for the purpose of obtaining information that cannot be derived from the individual studies.
Meta-analysis can be a helpful tool for generating hypotheses for future trials, for studying the consistency of trials of the same or similar goals, and for generating more precise estimates of effect. There are still a number of unresolved questions about the methodology and interpretation of meta-analysis. Better and more uniform reporting of primary studies would increase the usefulness of meta-analysis.
