highly significantP ≤ 0.05
Parameter P indicates the significance of a parameter (in this work, the parameter was the direction, X or Y ), where 0 ≤ P ≤ 0.01 indicates highly significant; 0.01 < P ≤ 0.05 indicates significant; 0.05 < P ≤0.20 indicates weakly significant; 0.20 < P ≤ 1 indicates not significant.
