Requests clarification on study of surgical removal of mast cell tumors

I read with interest the article “Association of histologic tumor characteristics and size of surgical margins with clinical outcome after surgical removal of cutaneous mast cell tumors in dogs” by Schultheiss et al.1 As pointed out in the article, the current gold standard of 2-cm lateral margins can be difficult to achieve in many locations and it would be important to know whether narrower margins provide an equal statistical chance for cure.

My concern specifically relates to the authors' statement that “[n]o attempt was made to adjust
