Enum: TimepointRelation

Where an occasion sits relative to the intervention. Directional terms over these values mark an analysis as a within-person change rather than a cross-sectional comparison. Open vocabulary: write the source's own wording in the field when nothing here fits.

permissible_values:
  pre_intervention:
    text: pre_intervention
    description: Before the intervention was delivered -- a baseline or pre-treatment
      occasion.
  during_intervention:
    text: during_intervention
    description: While the intervention was in effect, including a scan under an acute
      drug challenge or during a stimulation train.
  post_intervention:
    text: post_intervention
    description: After the intervention was delivered. Covers both the occasion the
      study treats as its endpoint and any later follow-up testing whether an effect
      persisted; use `order` and `time_from_intervention` to separate several post
      occasions.
  single_occasion:
    text: single_occasion
    description: The study collected data once, so the occasion stands in no relation
      to an intervention.
  not_applicable:
    text: not_applicable
    description: Data were collected on several occasions but nothing was administered,
      so there is no intervention to be relative to. A longitudinal observational
      study takes this value.
