- Key for modified Newcastle-Ottawa domains:
- Selection:
- 1. Representativeness of the exposed cohort
- 2. Selection of the non-exposed cohort
- 3. Ascertainment of exposure
- 4. Demonstration that the outcome of interest was not present at the start of the study

- Outcome:
- 6. Assessment of outcome
- 7. Was follow-up long enough for outcomes to occur.
- 8. Adequacy of follow up of cohorts
- Red = Failed to satisify domain (Reduces quality)
- Amber = Moderately satisfied domain (moderately affects quality)
- Green = Satisfied domain (Increases quality)
