mb.make.contrast: Convert arm-based MBNMA data to contrast data

In MBNMAtime: Run Time-Course Model-Based Network Meta-Analysis (MBNMA) Models

Convert arm-based MBNMA data to contrast data

Description

Converts an object of class mb.network from arm-based long MBNMA data to a data frame with contrast data (a separate contrast for each treatment comparison at each time point within each study). Data can be either long or wide.

Usage

mb.make.contrast(network, datatype = NULL, format = "wide")

Arguments

network	An object of class mb.network
datatype	A string indicating the data type. Can be binomial or normal
format	A string indicating the data format. Can be wide (two additional columns for each variable - contrast arms) or long.

Value

A data frame with the following columns. In wide format, some columns are given the indices 1 and 2 to indicate each arm in a given treatment comparison.:

• t The treatment in each arm

• TE The treatment effect (mean difference, log-odds) for the treatment in arm 1 versus the treatment in arm 2

• seTE The standard error for the treatment effect (mean difference, log-odds) for the treatment in arm 1 versus the treatment in arm 2

• y The mean response in each arm

• se The standard error of the mean in each arm

• r The number of responders in each arm

• n The total number of participants in each arm

• fupcount Follow-up identifier

• time The time the data are reported

• studyID Study identifier

Examples

# Create mb.network
network <- mb.network(osteopain)

# Convert to wide contrast data
mb.make.contrast(network, format="wide")

# Convert to long contrast data
mb.make.contrast(network, format="long")
