  1. The significant p-values are printed in bold
  2. The parameters and their descriptions are analogous to those in Table 2. The p value of the nonparametric Mann‒Whitney for the independent observations test compares both groups and indicates a deficiency in the task time*, time to first positioning, efficiency of task solving, and the ITR for the patient group
