Figure 3. Combining predictive markers of neurodegeneration in idiopathic RBD.

Figure 3

Shown is the Kaplan-Meier plot of disease-free survival of patients with idiopathic REM sleep behavior disorder (RBD), stratified according to combinations of baseline markers: (A) removing antidepressant-triggered RBD and age 55 years and older; (B) addition of olfaction and motor combined; (C) addition of olfaction and color vision combined; and (D) addition of motor and color vision combined. Solid line indicates patients with normal values, dashed lines mean that 1 of 2 measures is abnormal, dotted lines mean both measures are abnormal.
