  1. Mahalanobis Distance (MD) demonstrated the distance between the bivariate data of two cognitive groups (assuming normal distribution) with the evaluation of statistical significance using Hotelling’s T2 test. Presented in boldface for the MD with *p < 0.05, **p < 0.01, ***p < 0.001.
  2. R/H and Xc/H represent height-normalized resistance and reactance.
