Nutrition Users' Guides



Please note, unlike many appraisal tools the links to the tools below uniquely provide guidance on (i) risk of bias assessment, as well as (ii) interpreting the magnitude of effect for study results and (iii) applying the study results based on patient or population health-related values and preferences.

Users’ Guides to the Nutrition Literature

  • Introduction to series

  • Randomized clinical trials – part 1 – risk of bias

  • Randomized clinical trials – part 2 – study results (magnitude of effect) and applicability

  • Systematic reviews – risk of bias, study results, and applicability
