Full text of the below study is really required in order to truly discuss the results.
I hope the full text version spends some time addressing the subjects ability to read. I also hope the investigators provide a rationale for 15 sessions of physical therapy. As with most comparative studies, I also expect a description of what "physical therapy" entailed.
I tend to do better sharing my thoughts if I can review the findings within the full text. I don't quite understand "noninferiority margins." I'm not quite sure why the investigators didn't just use the minimal clinically important difference.
Below you will find a quick view of the abstract.
