title: Meta-analysis: Forest plot of summary estimates using metafor package
body: <p>I am meta-analysing data from ~90 studies. This presents some challenges in how to display the data in an accessible format for publication. I would like to display only the overall effect size estimates of the different meta-analyses and exclude the study-specific estimates. I am able to do this in Stata using the <code>metan</code> package and adding the <code>summaryonly</code> command. Is it possible to suppress the study-level effect sizes in the forest plot outputs using the <code>metafor</code> package (or any other meta-analysis R package)?</p>
  
  <p>I've been using the <code>addpoly</code> command to add the effect size estimates for sub-samples as described in the package documentation, e.g.:</p>
  
  <pre><code>res.a &lt;- rma(n1i = Intervention_n, n2i = Control_n, m1i = intervention_d, m2i = control_d, sd1i = intervention_d_sd, 
           sd2i = control_d_sd, measure="MD", intercept=TRUE, data = Dataset.a, vtype="LS", method="DL", level=95, 
           digits=4, subset = (exclude==0 &amp; child=="No"), slab=paste(Dataset.a$Label, Dataset.a$Year, sep=", "))
  addpoly(res.a, row=7.5, cex=.75, font=3, mlab="Random effects model for subgroup")
  </code></pre>
