Clearly the author didn&#x27;t find the results from the paper you pointed to particularly compelling.  It&#x27;s listed as reference 136 and mentioned several times.  The last of which, &quot;In the absence of more precise knowledge of the extents of analgesic consumption and the durations of exposure, the reliability of these reports [45, 136, 137] is open to question.&quot;  Is there a reason you find the Stewart paper to be more definitive than this author suggests?
