Comparing derivations: results from both five-minute periods.

The first two columns indicate the analyzed five-minute periods and derivations. Subsequent columns show, for each period and derivation, group means of slow-wave amplitude (SWA, in µV) and its derivation-dependent component (SWAD), followed by the same means but now relative to the mean of the C4-M1 derivation, and finally the coefficient of variation (CV) of SWAD. Brackets in the third and last column contain SWAD's 95% confidence interval and Max/Min ratio, respectively.
