Following publication of the original article [1], the author notified us about incorrectly formatted of Table 2 and Table 3. Also, about the incorrectly displayed of the values and the corresponding unit. The original version of this article was revised.

The correct format of the tables is presented below.

Table 2

  • The time effect p-value (11 changes required) should be placed below the corresponding mean±SD-values. The values are always aligned to the right side of the columns.

  • The effect size-values and p-values account should be for the time point T1 only. The effect sizes (11 changes required) and p-values (11 changes required) values should be placed at the same line as “T1”.

Table 3

  • The effect size-values and p-values account should be for the time point T1 only. The effect sizes (12 changes required) and p-values (12 changes required) values should to be placed at the same line as “T1”.

The visibility of the tables was also improved.

The values and the corresponding units should be displayed in one line.
