 Group analysis of VOSP subtests (mean and standard deviation) in the three patient groups and in the control group

Subtest (max score)ControlsMSAPSPCBDF
*Impaired relative to controls.
†Impaired relative to MSA patients.
‡Impaired relative to PSP patients.
In all six subtests the differences between the groups are significant with a p<0.01.
