The authors wish to correct a typographical error in the
manuscript. In both the abstract and Section 3.4 of the original manuscript, a
1-point increase in the Dublin-Boston score was described as being associated
with a 5.6 times increased odds (OR 5.62, 95% CI = 3.229.81, P = 1.2 £ 109 )
for a more severe outcome. While the OR and P-value stated are correct, the CI
should instead have read “3.229.81”. The CI listed in Table 3 of the original
manuscript, which accompanied Section 3.4, is correct. The authors regret any
confusion caused, and appreciate the opportunity to correct this mistake.</div
