Amlodipine for Work Capacity


Meta-analysis on the effect of amlodipine on work capacity.

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


A data frame with the following columns:

study study label
n.amlo number of observations in amlodipine group
mean.amlo estimated mean in amlodipine group
var.amlo variance in amlodipine group
n.plac number of observations in placebo group
mean.plac estimated mean in placebo group
var.plac variance in placebo group
