In Box 1 of the originally published article, Jong Seok Bae should have been included as a member of the GBS Classification Group. Also, in Table 2, the row title 'Bifacial weakness with distal paraesthesias' should have read 'Bifacial weakness with paraesthesias'. These errors have been corrected in the HTML and PDF versions of the article.
