The result of ROC analysis distinguishes between NC and AD for each item

	AUC	SE	p	Cut off	Specificity	Sensitivity
TNF-α	0.694	0.120	0.136	0.810 pg/mL	55.6%	66.7%
cortisol	0.519	0.133	0.887	27.0μg/dL	55.6%	50.0%
ACTH	0.519	0.132	0.887	38.0 pg/mL	66.7%	58.3%
HCA	0.806	0.111	0.019	0.116μM	77.8%	83.3%
tau	0.861	0.088	0.006	17.00 pg/mL	88.9%	83.3%
p-tau	0.944	0.051	0.001	5.30 pg/mL	88.9%	100.0%

The AUC and the optimal cutoff when writing the ROC curve that distinguish between NC and AD are shown with the sensitivity and specificity at that time.
