<p>Hi Wolfgang,</p>
<p><br>
</p>
<p>Many thanks for your previous email specifying that I needed to include two random effects instead of just one, and to calculate a covariance matrix due to correlation between OR estimates due to the use of the same control group for multiple treatment groups.</p>
<p><br>
</p>
<p>I would be grateful if you could check my current models. I have attached code for two different models---the lameness one included studies with multiple treatment arms, and the anorexia one did not. </p>
<p><br>
</p>
<p>Thanks in advance,</p>
<p><br>
</p>
<p>Nadine Vogt</p>
