Two row labels and two data items in each of these rows in Table 1 were misplaced and this affects one of the reported results. The corrected Table is reproduced below, with the altered data shown in bold. The change to the results concerns the ninth paragraph of the Results, referring to these data in Table 1.

aMultiple organisms can be isolated from one patient, hence the sum of n is >112.
The original text read ‘There was a trend towards better outcomes in patients with a longer time between presentation and debridement (Table 1) on univariate analysis. However, the significance was marginal …’. The text should read ‘There was a trend towards worse outcomes in patients with a longer time between presentation and debridement (Table 1) on univariate analysis.
