Stepwise multivariable logistical regression analysis to predict NPH from non-NPH (HC, PD, AD) groups with brain MRI measures as independent factors

Characteristic	Receiver operating characteristics (95% confidence interval)
EI	0.902 (0.833, 0.971)
CA	0.971 (0.940, 1.000)
SA	0.990 (0.971, 1.000)
SA + EI	0.989 (0.971, 1.000)
SA + CA	0.992 (0.976, 1.000)
EI + CA + SA	0.990 (0.973, 1.000)

Note: HC healthy controls, PD Parkinson’s disease, AD Alzheimer’s disease, NPH idiopathic normal pressure hydrocephalus, EI Evans’ index, CA callosal angle, SA splenial angle
