^a The Spearman correlations are between counts/min derived for the ActiGraph and the 3 Android smartphones (Motorola Cliq, HTC MyTouch, and Google/HTC Nexus One).

^b The different models correspond to different filters (ie, no bike & standing excludes bicycling and standing; hip-only excludes measures whereby the phones were in the pocket).
