a statistical trendP = 0.06
The amplitude of slow-waves revealed a statistical trend for the factor condition ( F 1,65 = 3.78, P = 0.06, η p = 0.05), while the up-slope ( F 1,65 = 0.01, P > 0.90), mean frequency ( F 1,65 = 0.44, P > 0.50) and duration ( F 1,65 = 0.36, P > 0.50) of slow-waves were comparable between conditions.
