Network Meta-Analysis of Smoking Cessation

Description

An illustrative example of network meta-analysis with a binary outcome.

Usage

data("dat.sc")

Format

A data frame containing 24 studies and 4 treatments, with the following 4 variables.

sid

a numeric vector indicating study IDs.

tid

a numeric vector indicating treatment IDs.

e

a numeric vector indicating event counts.

n

a numeric vector indicating sample sizes.

Details

The dataset was originally reported by Hasselblad (1998) and reanalyzed by Lu and Ades (2006) using formal network meta-analysis methods. It investigates the effects of four treatments on smoking cessation, including 1) no contact; 2) self-help; 3) individual counseling; and 4) group counseling. The outcome is binary, which is the smoking cessation status (yes or no) of a participant after treatment.
