In poth: Precision of Treatment Hierarchy (POTH)

Generate reference distribution for POTH for a given network structure

Description

Generate reference distribution for POTH for a given network structure

Usage

refdist(x, d, pooled, nsim = 25, verbose = TRUE)

## S3 method for class 'refdist'
print(x, ...)

## S3 method for class 'refdist'
summary(object, ...)

Arguments

x	A netmeta object.
d	A vector of the desired relative effects, must be in the same order as x$trts.
pooled	A character string indicating whether the treatment hierarchy is based on a common or random effects model. Either "common" or "random", can be abbreviated.
nsim	Number of samples from reference distribution.
verbose	A logical indicating whether progress information should be printed.
...	Additional arguments passed on to print or summary function.
object	A refdist object.

Details

By default, argument pooled is equal to "random" if only the random effects model was considered in the network meta-analysis x. Otherwise, argument pooled is equal to "common".

If argument d is missing, the respective relative effects are taken to be all 0.

Value

A vector of POTH values.

Examples

library("netmeta")
data(Senn2013)
net1 <- netmeta(TE, seTE, treat1.long, treat2.long, studlab,
  data = Senn2013,
  sm = "MD")

# POTH (based on common effects model)
poth(net1)

# Sample POTH values from reference distribution (common effects model)
set.seed(1909)
poths <- refdist(net1)
summary(poths)

# POTH (based on random effects model)
poth(net1, pooled = "random")

# Sample POTH values from reference distribution (common effect model)
poths.r <- refdist(net1, pooled = "random")
summary(poths.r)
