Create a summary risk of bias plot

createRobSummary.Rd

If the rob.data argument has been specified, this function allows to create a summary risk of bias plot for results of the runMetaAnalysis() function.

Usage

createRobSummary(model, 
                 name.low, 
                 name.high, 
                 name.unclear, 
                 which.run = model$which.run[1])

Arguments

model

An object of class runMetaAnalysis, created by the runMetaAnalysis() function.

name.low

A character vector, specifying which code(s) have been used in the original data for studies with a low risk of bias.

name.high

A character vector, specifying which code(s) have been used in the original data for studies with a high risk of bias.

name.unclear

A character vector, specifying which code(s) have been used in the original data for studies with unclear risk of bias.

which.run

The model in model that should be used for the summary risk of bias plot. Uses the default analysis in model if no value is specified by the user. Possible values are "overall", "combined", "lowest", "highest", "outliers", "influence" and "rob".

Value

Creates a RevMan-type risk of bias summary plot.
