<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">treatment plan</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for regimen that I've seen before include "prescribed treatment" , "Plan for e.g. diet" , "discipline" , "Method of working" , "recommended diet" .)
