Receiver operating characteristic curves for Useful Field of View
(UFOV) Subtests 1, 2, and 3; UFOV RI; and Trail Making Test Part B
with three arbitrarily chosen cutpoints for UFOV 2, UFOV RI, and
Trails B (N = 198).
Note. UFOV risk = UFOV Risk Index; 50%
probability is the diagonal dotted line indicating that the area
under the curve = 50%.
