LZC= Lempel-Ziv Complexity, ρ= Entropy rate

^†

= Statistical difference between A-P and M-L axes

^‡

= Statistical difference between S-I and M-L axes

^§

= Statistical difference between A-P and S-I axes

Values were statistically significant when probability is less than 0.05 (p-value < 0.05).
