A meta-analysis starts with a systematic review. A systematic review is a scientiﬁc summary of all available evidence on a speciﬁc research question. An exhaustive search of the literature will require more than R. Note: If available studies are too few or too different a meta-analysis may not be appropriate. · · · · 11/204

Consequently, more bonds need to. In order to reach a state of stability, atoms bond together to form molecules by sharing their valence electrons, or electrons that make up the outermost shell.

These approaches can use either a fixed-effects or a random-effects statistical model. A fixed-effects meta-analysis assumes that all of the studies included are estimating the same (fixed) treatment effect, or incidence rate in this case, whereas a random-effects meta-analysis allows for differences in the outcome between studies.

Meta-analysis allows researchers to combine results of several studies into a unified analysis that provides an overall estimate of the effect of interest and to quantify the uncertainty of that estimate. Stata has some of the best statistical tools available for doing meta-analysis.
