doi: 10.1186/1471-2458-14-519

Figure Lengend Snippet: Ratio of activity monitor steps to manually counted steps at each stage

Article Snippet: When all stages were combined, all monitors showed significant associations with manually counted steps, with coefficients of determination ranging from 0.86 (Actical and ActiGraph GT3X) to 0.89 (Walk4Life MVP) (all p < 0.05).
