(a) Receiver operator characteristics (ROC) curves for monocular tests/criteria of cVEP(60′), cVEP(15′), mfVEP(latency), mfVEP(percent abnormal), and mfVEP(cluster). (b) ROC curves for interocular tests/criteria of cVEP(60′), cVEP(15′), mfVEP(latency), mfVEP(percent abnormal) and mfVEP(cluster). (c) ROC curves for monocular tests/criteria for region of good specificity (10%), within rectangle in (a). (d) ROC curves for interocular tests/criteria for region of good specificity (10%), within rectangle in (b)
