Baker et al. International Journal of Behavioral Nutrition and Physical Activity 2010, 7:51 http://www.ijbnpa.org/content/7/1/51 Open Access CORRECTION The effect of a pedometer-based community walking intervention "Walking for Wellbeing in the West" on physical activity levels and health outcomes: a 12-week randomized controlled trial Correction Graham Baker*, Stuart R Gray, Annemarie Wright, Claire Fitzsimons, Myra Nimmo, Ruth Lowry, Nanette Mutrie for the Scottish Physical Activity Research Collaboration (SPARColl) 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: In the results section of the manuscript the median differences presented in the text for the Wilcoxon's signedrank tests in the intervention group should be, 1. Leisure minutes walked: "60" not "100" 2. Weekday sitting: "- 300" not "1200" 3. Weekend sitting: "- 120" not "360" 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. 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)."
