On account of a marginally significant correlation between ND enhancement of supra-threshold connectivity of the alpha band and the ND-MF of postural fluctuations ( r = 0.307, p = 0.073), a further detailed correlation analysis was performed with consideration of the ND enhancement of the supra-threshold connectivity of the alpha band from the three key nodes (O 2 , P z , and Fp 2 ) ( Table 4 ; Figure 5B ).
