Enum: ArmKind¶
What class of thing an arm received. Spans both the manipulation and the thing it was compared against, both being arms here: a drug against an active comparator is a different comparison from a drug against a placebo, so the two take different values. Open vocabulary: write the source's own wording in the field when nothing here fits.
