ROC curve analysis of spike number and jitter using concentric needles to differentiate ALS patients from healthy controls. The dotted line indicated the ROC curve of the mean spike number using concentric needles. The black line indicated the ROC curve of the mean jitter using concentric needles. Both ROC curves showed the high area under curve values (0.966 for the mean spike number and 0.871 for the mean jitter). ROC: Receiver operating characteristic. ALS: Amyotrophic lateral sclerosis.
