Table 2. Tests of fixed effects for LMEM on PSD power peak at 4.05Hz.
Results reported for separate LMEMs run on the first half, second half and full sample of data. Significant results (p<0.05) denoted by bold italic text. The Satterthwaite approximation was applied to approximate the degrees of freedom, due to the missing cases.
