Spotlight on Methods – Webinars of the European Cochrane Groups

In these one-hour live webinars, our experts present selected topics on the methods used to produce and utilise evidence synthesis, focusing on new methods and recent developments. The topics and presenters are chosen in turn by a European Cochrane Group. The webinars also provide a forum for discussing current methodological challenges in review work and exchanging ideas.

  • Participation is free of charge.
  • We use Zoom – further information on its use can be found here.
  • Registration is required.

Topic: Assessing the Certainty of the Evidence by Means of Absolute Estimates of Effect: the New GRADE Approach
Speaker: Silvia Minozzi (MD, MSc) & Francesco Nonino (MD, MSc)
 
According to the new GRADE approach, "Certainty of the Evidence" refers to the confidence that effect estimates fall within a specific range or above a particular absolute threshold of interest.
The new GRADE GUIDANCE recommends to predefine decisional thresholds to determine trivial, small, moderate, and large effects (desirable as well as undesirable). These values are developed by determining an outcome-specific expected utility values and combining it with an empirically derived generic coefficient. The new GRADE method will allow systematic review authors assessing imprecision of any effect estimate by evaluating how its absolute value and its confidence intervals relate to predefined outcome-specific decisional thresholds, therefore moving forward from a limited, non-contextualised framework where imprecision was only assessed in relation to the null effect.
The webinar will address the theoretical framework by illustrating the GRADE guidance  42 (Wojtek et al 2025) and its application in a recently submitted Cochrane review of effect on disease-modifying treatments for Alzheimer’s disease.
