We classified activity level as sleep or marked physical inactivity (i.e., a VM of 0–500), light physical activity (VM of 501–2689), and moderate or greater physical activity (VM ≥2,690) [21]. A VM score of 0–500 was taken to indicate sleep or marked physical inactivity based upon our observations of the subjects’ activities when these readings were obtained.","tracks":[{"project":"2_test","denotations":[{"id":"24777474-21616714-56346672","span":{"begin":382,"end":384},"obj":"21616714"}],"attributes":[{"subj":"24777474-21616714-56346672","pred":"source","obj":"2_test"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"2_test","color":"#93ecb9","default":true}]}]}}
