7. GRADE and diagnostic testing

The GRADE system can be used to grade the quality of evidence and strength of recommendations for diagnostic tests or strategies. There are still a number of limitations and problems that are not entirely solved yet. However, there are some informative publications coming from the GRADE working group on this topic to guide authors of systematic reviews and guideline developers using GRADE to assess the quality of a body of evidence from diagnostic test accuracy (DTA) studies (Schünemann 2008, Brozek 2009, Hsu 2011, Schünemann 2016). People from the GRADE working group continue to publish on GRADE for diagnostic testing, see for example Journal of Clinical Epidemiology Volume 92 (December 2017) .
