Table 5. Tests of fixed effects generated from LMEM, assess how PAC (nMI) varied across data types (real or random nMI values), low-frequency phase (LFP), high-frequency amplitude (HFA) and age (4-, 7- or 11-months).

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.
