How can I catch empty result of [events_list]?

In my taxonomy template, I have the following code:

<div class="row">
   <?php
   echo do_shortcode('[events_list scope="future" limit="10" category="'.$EM_Category->output('#_CATEGORYID').'"][/events_list]');
   ?>
</div>

How can I catch with php with an if else construction if an empty result is returned? I would like to display custom HTML if no results are returned.
