Slot: arm
The arm this cohort was allocated to. Set it whenever a cohort was allocated to one, which is the parallel-group case: every participant of this cohort received this arm and no other. A crossover study allocates nobody to one arm, so its cohorts leave this empty and an arm reaches an analysis only as a level of a model term, through FactorLevel.arms. Distinct from medication_status, which is the on/off state during acquisition rather than the allocation.
