Methodology for automation of this process has become proposed[61] but requires that arm-degree outcome facts are available, which is often unavailable. Good promises are occasionally made for the inherent potential of your Bayesian framework to deal with community meta-analysis and its bigger adaptability. Nevertheless, this selection of implementation of framework for inference, Bayesian or frequentist, can be less significant than other alternatives regarding the modeling of consequences[sixty two] (see discussion on designs higher than).
