Figure 2. State-like and trait-like properties of the F/O-ratio of slow wave activity (n=13 for T1, n=14 for T2).

Figure 2.

A. F/O-ratio comparison between T1 and T2 (p=0.001, Wilcoxon Signed Rank Test). Mean and Standard Deviation are presented for both time points, next to individual data. B. F/O-ratio illustrated for effective age at T1 (Rho=0.75, p=0.005). C. F/O-ratio was not related to effective age at T2 (Rho=0.41 p=0.14). D. Linear association between F/O-ratio at T1 with T2 reached significance only with inclusion of ‘age’ as control variable (Rho= −0.15, p=0.63; partial correlation factor ‘age at T2’: Rho= −0.60, p=0.04). Results were consistent with exclusion of the subject with T2 assessment only (n=13: p=0.001 for panel A; Rho=0.32 p=0.28 for panel C; no change in panels B and D).
