  1. GRADE Working Group grades of evidence
  2. High quality: We are very confident that the true effect lies close to that of the estimate of the effect
  3. Moderate quality: We are moderately confident in the effect estimate: The true effect is likely to be close to the estimate of the effect, but there is a possibility that it is substantially different
  4. Low quality: Our confidence in the effect estimate is limited: The true effect may be substantially different from the estimate of the effect
  5. Very low quality: We have very little confidence in the effect estimate: The true effect is likely to be substantially different from the estimate of effect
