Correction

Since publication of our article[1] we have found some imputation errors in the main text and Table Four (Table 1) and Table Five (Table 2) corresponding to the 12-week results. The corrections are as follows:

Values are median (Mdn) and range (r).

In the results section of the manuscript the median differences presented in the text for the Wilcoxon's signed-rank tests in the intervention group should be,
  1. 1.

    Leisure minutes walked: "60" not "100"

     
  2. 2.

    Weekday sitting: "- 300" not "1200"

     
  3. 3.

    Weekend sitting: "- 120" not "360"

     
  4. 4.

    Total sitting: "- 300" not "1680"

     
In the results section of the manuscript the median difference presented for the Mann Whitney U test at week 12 between groups should be,
  1. 1.

    Total minutes walked: "135" not "57.5"

     

As a consequence of the amendment to the median leisure minutes walked in the intervention group the following sentence from the discussion should be corrected as follows:

Original Sentence

"The increase observed in the step-count data was supported by the self-reported results of the IPAQ; a significant increase in reported minutes of leisure time walking was found in the intervention group (median increase of 100 minutes per/week)."

Amended Sentence

"The increase observed in the step-count data was supported by the self-reported results of the IPAQ; a significant increase in reported minutes of leisure time walking was found in the intervention group (median increase of 60 minutes per/week)."
