# 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.
#
pw1 <- pairwise(treatment, death, n, studlab = study,
  data = dat.gurusamy2011, sm = "OR")

# Conduct Mantel-Haenszel network meta-analysis
