</h3>
<p>We follow the data set’s help file and fit a simple random effects
meta-analysis using the <code>rma()</code> function from
<code>metafor</code> package. This model ignores the dependency between
effect size estimates. We use this simple model as our starting point
and as a comparison with the later models.</p>
