The control group (n = 41; thin solid line with black circles) displayed low POMS TA, D, A, F, and C scores and a high POMS V score. The high-ALS group (n = 20, thick solid line with triangles) displayed high POMS TA, D, A, F, and C scores and a low POMS V score. The low-ALS group (n = 39, broken line with squares) displayed moderate POMS scores. POMS = Profile of Mood States; TA = tension-anxiety; D = depressive mood or discouragement; A = anger-hostility; F = fatigue-inertia; C = confusion-bewilderment; V = vigor-activity; ALS = autonomic lability score.
