Abstract
The original version of this article, unfortunately, contained errors. The p value columns in Tables 2 and 3 were inadvertently shifted up by one row during the copy editing process. Therefore all p values as published in these tables did not correspond to their correct data variables and thereby misrepresented the results of statistical analysis. The updated published version of this article has now corrected the p value columns in Tables 2 and 3 such that all the previously misaligned p values do now properly correspond to their correct respective rows of variables as were present in the authors’ final submitted manuscript version. The original article was corrected. © Springer-Verlag GmbH Germany 2017.
