Please find the corrections below:
Anzeige
1) A 2.82 is missing in column VM.
2) The superscripts in column BPPV are superfluous, as the last two questions allow only one answer each, as detailed in the caption.
These corrections are included in the spreadsheet files we offered upon request in the article.
