The significant p-values are printed in bold
The trend separately describes the slope of the linear regression and its 95% confidence interval over three tests for each volunteer for the control and patient groups. The p value indicates whether the estimate of the slope is significantly different from zero (Wicoxon rank test). During test repetition, the task time* was significantly reduced, and the efficiency improved in the patient group
