Abstract
The values in Table 2 pre-treatment (column 1 and 2) differed from the reference values. It was subsequently determined that the linear regression equation used had an error.
In Table 2 below the authors re-analyzed the data for column 1 and 2 using the corrected equation and supplied the journal with the new values. The effect size and p-values remained unchanged.
In Table 3 the medians were re-calculated and supplied to the journal.
The Journal Editor confirmed after having them verified by the scientific experts/external reviewers that the change in values in Table 2 and 3 did not result in a change in the conclusions.
The authors apologize to readers for this inadvertent error.
