  1. Low: comparable to a well-performed randomized trial
  2. Moderate: sound for a non-randomized study, not comparable to a randomized trial
  3. Serious: presence of important problems; critical: too problematic to provide any useful evidence on the effects of intervention
  4. Overall risk of bias equal to the most severe level of bias found in any domain
