You may optionally set a PHP callback here to ascertain if this member stat should be displayed.<br />
<br />
Callback arguments:
<ol>
	<li>
		<code>\XF\Entity\MemberStat $memberStat</code>
		<br />
		This member stat entity.
	</li>
</ol>
The callback should return either <code>true</code> or <code>false</code>, where <code>false</code> will prevent the member stat from displaying.
