mb.nodesplit.comparisons: Identify comparisons in time-course MBNMA datasets that fulfil criteria for node-splitting

Description

Identify comparisons informed by both direct and indirect evidence from independent sources in MBNMA datasets with repeated measurements in each study. These comparisons are therefore those which fulfil the criteria for testing for inconsistency via node-splitting, following the method of van Valkenhoef vanvalkenhoef2016;textualMBNMAtime.

Usage

mb.nodesplit.comparisons(network)

Value

A data frame of comparisons that are informed by direct and indirect evidence from independent sources. Each row of the data frame is a different treatment comparison. Numerical codes in t1 and t2 correspond to treatment codes.

Arguments

network

An object of class "mb.network".

Details

Similar to gemtc::mtc.nodesplit() but uses a fixed reference treatment and therefore suggests fewer loops in which to test for inconsistency. Heterogeneity can also be parameterised as inconsistency and so testing for inconsistency in additional loops whilst changing the reference treatment would also be identifying heterogeneity. Depends on igraph.
