&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;Effect sizes can be log transformed on the fly. This is convenient when&lt;br /&gt;
meta-analyzing odds ratios. In this case, two studies have the same direction&lt;br /&gt;
of effect if their log(odds ratio) statistics are both positive or negative,&lt;br /&gt;
corresponding to odds ratios that are both &amp;gt;1.0 or &amp;lt;1.0.&lt;br /&gt;
&lt;br /&gt;
This transformation is activated through the EFFECTLABEL command. For example,&lt;br /&gt;
EFFECTLABEL log(ODDSRATIO) instructs metal to log-transform the ODDSRATIO column&lt;br /&gt;
prior to analysis.&lt;/div&gt;</summary>
