Search strategy
The task force searched three databases (Cochrane CENTRAL (Trials), MEDLINE (OVID) and Embase (OVID)) for diagnostic test accuracy studies published between 1st October 2012 and 30th June 2021. Manuscripts preceding this date were evaluated previously in the EAACI SR on diagnostic tests [8]. A manual SR search was performed by the task force and additional relevant references were found following suggestions from the EAACI expert panel group. For non-English language studies, a native speaker within the task force extracted and presented the relevant data for the group to reach a consensus on inclusion and assessment.
