TABLE 3.

Stage N3- and N2-specific slow wave and spindle event counts and percentage of late-fast slow wave/spindle pairs from each channel pairing among the DREAMS subjects.

EEG channel pair	N3 sleep mean weighted percent late-fast + slow waves (SD)	N2 sleep mean weighted percent late-fast + slow waves (SD)
FP1-CZ	59.93** (8.59)	49.25** (6.71)
CZ-CZ	53.15* (10.46)	48.08* (7.24)
FP1-FP1	64.99** (8.69)	53.04** (6.41)

SD, Standard Deviation.

For statistical comparison between the mean percent of late-fast spindles + slow wave events in N2 vs. N3 within channel pairs: *denotes P < 0.05, and **P < 0.0001.

Results for weighted values come from the statistical model.

The standard deviation corresponds to a weight of one, the average.
