Sensitivity and specificity of oculomotor parameters separated for PSP-RS and PSP-P

	Area under ROC-curve (PSP-RS/PSP-P)	Sensitivity (PSP-RS/PSP-P)	Specificity (PSP-RS/PSP-P)
VGRS (vertical) peak eye velocity, °/s	0.895/0.825	58.7%/50.0%	95.5%/97.7%
VGRS (up) peak eye velocity, °/s	0.906/0.865	66.0%/55.3%	97.7%/95.5%
VGRS (down) peak eye velocity, °/s	0.842/0.717	60.4%/51.3%	95.6%/97.8%
VGRS intrusion rate, °/s	0.946/0.895	63.0%/46.2%	95.6%/95.6%
VGRS vertical asymmetry	0.695/0.771	23.9%/44.4%	95.5%/95.5%

The calculation was performed by ROC analysis. The values given for sensitivity and specificity refer to the defined limit values
