*While social network theory can be readily applied in theoretical research and qualitative empirical studies, there is a general emphasis on the use of software to analyze and visualize network data once they have been collected. The analysis of network data is an area that is rapidly growing, both within and outside of the discipline of statistics. The total current through or the total voltage across a particular branch is then calculated by summing all the individual currents or voltages.*

Metrics details. Network meta-analysis NMA is becoming increasingly popular in systematic reviews and health technology assessments. However, there is still ambiguity concerning the properties of the estimation approaches as well as for the methods to evaluate the consistency assumption.

We use ideas from graph theory to derive the proportion that is contributed by each direct treatment effect.

We present an algorithm that identifies the flow of evidence in each path and decomposes it into direct comparisons. To illustrate the methodology, we use two published networks of interventions.

The first compares no treatment, quinolone antibiotics, non-quinolone antibiotics and antiseptics for underlying eardrum perforations and the second compares 14 antimanic drugs. We believe that this approach is a useful and novel addition to network meta-analysis methodology, which allows the consistent derivation of the proportion contributions of direct evidence from individual studies to network treatment effects.

Network topology is a graphical representation of electric circuits. It is useful for analyzing complex electric circuits by converting them into network graphs. Network topology is also called as Graph theory. Network graph is simply called as graph. It consists of a set of nodes connected by.

Jump to navigation. The mvmeta command in STATA employs a recent approach to network meta-analysis that handles the different treatment comparisons appeared in studies as different outcomes. The command can perform fixed and random effects network meta-analysis assuming either a common or different between-study variances across comparisons. The command contains also an option that enables the estimation of ranking probabilities. White IR.

### Description of network meta-analysis geometry: A metrics design study

The conduction and report of network meta-analysis NMA , including the presentation of the network-plot, should be transparent. We aimed to propose metrics adapted from graph theory and social network-analysis literature to numerically describe NMA geometry. A previous systematic review of NMAs of pharmacological interventions was performed. Network-plots were reproduced using Gephi 0.
