Shortened Measurement Time of Functional Visual Acuity for Screening Visual Function

Figure 5

The Bland–Altman plot shows agreement between the average response time (ART) measured using the standard- and short-version methods. The solid line shows the mean difference, and dashed lines show the 95% limits of agreement. Several plots overlap. 30 ART = ART measured using the short-version method; 60 ART = ART measured using the standard-version method.
