cisapride {meta}

Cisapride in Non-Ulcer Dispepsia

Description

Meta-analysis on cisapride in non-ulcer dispepsia.

This meta-analysis is used as a data example in Hartung and Knapp (2001).

Format

A data frame with the following columns:

study	study label
event.cisa	number of events in cisapride group
n.cisa	number of observations in cisapride group
event.plac	number of events in placebo group
n.plac	number of observations in placebo group
