In the original version of this article, Table 2 contained a number of erroneous values in the row “>24–48 h (n = 10)”. The values “22, 26%”, “15, 18%”, and “7, 8%” have now been corrected to “4, 40%”, “0, 0%”, and “1, 10%”, respectively. Additionally, in the results section, the authors mistakenly stated that “…50% of patients examined at 4 h or less converted by at least two grades in comparison with 15% of patients examined at more than 4 h (RR = 3.3, p = 0.03)”. This sentence has now been corrected to: “...50% of patients examined at 4 h or less converted by at least two grades in comparison with 21% of patients examined at more than 4 h (RR = 2.4, p = 0.04)”. This has been corrected in both the PDF and HTML versions of the article.
