Relationship between differences in steps per day and waist circumference.

<p>The difference in steps per day, expressed as a percent difference, is plotted by waist circumference. The correlation coefficients and 95% confidence intervals are for the relationships between percent difference in steps per day and waist circumference. A significant correlation indicates a relationship between percent difference in steps per day and waist circumference. <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0018942#pone-0018942-g002" target="_blank">Figure 2A</a> shows the relationship between the percent difference in AX120 hip-worn pedometer and the AMP-331 ankle-worn accelerometer (expressed as a percentage of the AMP-331) steps per day and waist circumference. <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0018942#pone-0018942-g002" target="_blank">Figure 2B</a> shows the relationship between the percent difference in AMP-331 ankle-worn accelerometer and MTI hip-worn accelerometer (expressed as a percentage of the MTI) steps per day and waist circumference. <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0018942#pone-0018942-g002" target="_blank">Figure 2C</a> shows the relationship between the percent difference in AX120 hip-worn pedometer and the MTI hip-worn accelerometer (expressed as a percentage of the MTI) steps per day and waist circumference.
