Sample text

If the HR < 1, then the outcome favors treatment A. 0 above, we have discussed the background and the major tests for determining the overall treatment effect and its significance as well as heterogeneity in meta-analysis. There are other topics that one can pursue which are informative and will point out precautions that one must take in discussing metaanalyses. 5 Survival comparison of A vs. B for time to event data One possible test is that of interaction. This involves grouping studies according to some characteristic of the study; for example, is the treatment effect homogeneous over the groups such as age categories, modalities, etc.?

However, for many studies the data are too old, too expensive to retrieve, or cannot be retrieved. A meta-analysis of aggregate data may be all that is possible. The statistical tools are such that most sources of bias and heterogeneity can be statistically examined. Sensitivity of statistically significant results can be measured. The statistical techniques to analyze results from meta-analyses are generally not new and many standard techniques apply. The resources to help accomplish a systematic review of studies to be included in the meta-analysis are available.

One should certainly be aware of these issues. The attempt has been made here to demonstrate most of the strengths and limitations of meta-analyses by way of definition and application. 1 Conclusion and Resources Meta-analysis is controversial. However, every attempt is made to guard against bias through proper systematic review, examination of heterogeneity, and publication bias. Heterogeneity should be exposed, explored, and explained if feasible. Limitations obviously result from selection of studies, choice of relevant outcome, methods of analysis, interpretation of heterogeneity, and 2 Overview, Strengths, and Limitations of Systematic Reviews and Meta-Analyses generalization and application of results.
