Correction to: Scand J Trauma Resusc Emerg Med https://doi.org/10.1186/s13049-020-00773-2

Following the publication of the original article [1], the authors became aware of two issues they would like to communicate to the readers:

  1. 1)

    In Fig. 1, second column, the number in the ‘Studies included’ box shows 9 instead of 8. The correct figure is included in this Correction.

  2. 2)

    In the ‘Study selection’ section, the symbol for the Kappa Coefficient shows up blank instead of (κ).
