In netmeta: Network Meta-Analysis using Frequentist Methods

Network meta-analysis of antithrombotic treatments in patients with non-valvular atrial fibrillation

Description

This dataset comes from a systematic review aiming to determine the effects of eight antithrombotic treatments in reducing the incidence of major thrombotic events in patients with non-valvular atrial fibrillation (Dogliotti et al., 2014). The review included 20 studies (79,808 participants), four of which were three-arm studies. The primary outcome is stroke reduction.

Format

A data frame with the following columns:

study	study label
id	study ID
treatment	treatment
stroke	number of strokes
total	number of individuals in treatment arm

Note

The dataset Dogliotti2014 is identical to dataset dat.dogliotti2014 in R package metadat.

# 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, stroke, total, studlab = study,
  data = dat.dogliotti2014, sm = "OR")

# Conduct Mantel-Haenszel network meta-analysis
