Erratum
During production of the original article [1] the Methods section included an incorrect sentence. The following sentence “For the analysis of variables with numerical distribution, Fisher’s exact test and one-way analysis of variance were used” should be corrected as “For the analysis of variables with numerical distribution, Student’s t-test and one-way analysis of variance were used”.
