Correlations and agreements between the 15-min and the 90-s CVAT’s versions. (a) VRT regression between 90 s and 15 min: Person correlation indicates a significant correlation between the two versions in the VRT data. (b) RT regression between 90 s and 15 min: Person correlation shows a significant correlation between the two versions. (c) ICC: the graphic shows a significant interclass correlation(p = 0.048) between the two CVAT versions for the VRT variable. (d) Bland–Altman of VRT: Bland–Altman plot for values of VRT for 15-min and 90-s tests indicates that values are distributed around the mean value for the differences and inside the 95% confidence interval. VRT variability of reaction time, ICC intraclass correlation.
