Examples

data(Dong2013)

# Only consider first ten studies (to reduce runtime of example)
#
first10 <- subset(Dong2013, id <= 10)

# Transform data from long arm-based format to contrast-based
# format. Argument 'sm' has to be used for odds ratio as summary
# measure; by default the risk ratio is used in the metabin
# function called internally.
#
p1 <- pairwise(treatment, death, randomized, studlab = id,
  data = first10, sm = "OR")

# Conduct Mantel-Haenszel network meta-analysis
#
netmetabin(p1, ref = "plac")

## Not run: 
# Conduct Mantel-Haenszel network meta-analysis for the whole
# dataset
#
p2 <- pairwise(treatment, death, randomized, studlab = id,
  data = Dong2013, sm = "OR")
netmetabin(p2, ref = "plac")

## End(Not run)
