Table 1. Epoch-by-epoch analysis for each state (including wake, transitional sleep, and relaxed sleep) showing total duration (min) and corresponding percentage (%) of epochs scored in agreement (diagonal from left to right) between videography (rows) and actigraphy (columns) methods and those scored differently by actigraphy analysis.

Wake	1 104	3 290	5 515		11.141	33.202	55.656
Transitional sleep	26	800	13 134		0.186	5.731	94.083
Relaxed sleep	34	611	25 886		0.128	2.303	97.569
