It has come to our attention that there are errors on page 4067 of the published paper. Specifically, Figure 1 and in the Results, Demographic Data of Study Groups section.
Figure 1.
Flow chart of the study design.
There are spelling errors throughout the figure artwork. The text “swaps” should read “swabs” and “d-dimmer” should read “D-Dimer”. The correct Figure 1 is shown below.
Results, Demographic Data of Study Groups section, left column, line 13, the text “P = 0 0.7” should read “P = 0.7”.
The authors apologize for these errors and advise they do not affect the results of the paper.
