On the other hand, there is an important limitation of standard meta-analysis only two interventions can be compared at a time. Since it makes it possible to combine data from many different studies so that a total estimate of treatment effect can be provided, a meta-analysis integrated into a systematic review is generally seen to be a useful statistical tool. A randomized, controlled trials used to compare different treatment options are generally seen to be infeasible, there is a need for other methodological approaches. An increasing number of options for alternative medical treatment has given rise to the need for comparative effectiveness research. Meta-analysis is used to synthesize the results of more than one study and overall effect size is considered to be valid only when some required assumptions are satisfied. The aim of the article is to compare the basic concepts and analyzes of network meta-analysis using diabetes data and the treatment methods used. In this chapter, the terms used in NMA are defined, relevant statistical concepts are summarized, and the NMA analytic process based on the frequentist and Bayesian framework is illustrated using the R program and an example of a network involving diabetes treatments.

Statistical approaches to NMA are largely classified as frequentist and Bayesian frameworks Because part of NMA has indirect, multiple comparisons, As reports of network meta-analysis become more common, it is essential to introduce the approach to readers and to provide guidance as to how to interpret the results. In general, network meta-analysis (NMA) offers the advantage of enabling the combined assessment of more than two treatments. Pairwise, Multivariate and Network Meta-analysis. There are three common types of meta-analysis.

Meta-analysis is a quantitative method commonly used to combine the results of multiple studies in the medical and social sciences. The objective of a meta-analysis is usually to estimate the overall treatment effect and make inferences about the difference between the effects of the two treatments.
