  • GRADE working group grades of evidence.

  • High certainty: We are very confident that the true effect lies close to that of the estimated effect.

  • Moderate certainty: We are moderately confident in the effect estimate: The true effect is likely to be close to the estimated effect, but there is a possibility that it is different.

  • Low certainty: Our confidence in the effect estimate is limited: The true effect may be substantially different from the estimate of the effect.

  • Very low certainty: We have very little confidence in the effect estimate: The true effect is likely to be substantially different from the estimate of effect.

  • GRADE, Grading of Recommendations Assessment, Development, and Evaluation; ID, intellectual disability.
