Stable significantly independent key features, selected for classification of Trustworthy (N = 63) and Concerning (N = 24) procedures for UVA (all selected features are from γ frequency band). A two-sample t-test is applied for significance evaluation. Feature values are represented as mean ± standard error- standard deviation divided by the square root of number of data. ^****Indicates correction multiplication test rejects null hypothesis and feature is significantly independent from other features with p-value ≤ 0.0001.

Feature Name	Trustworthy Feature Value	Concerning Feature Value	P-value
