Uncorrected mean (standard deviation) subcortical volumes in ml are displayed. For converters, volumes at time of conversion are measured. For non-converters and controls, mean volumes across visits were calculated. Results of a one-way analysis of covariance (ANCOVA) for group differences with age, gender and intracranial volume as covariates. Significant difference between converters and non-converters is displayed in Italic.
aPost-hoc analyses were adjusted for multiple comparisons using a Bonferonni correction
*Significant difference compared to controls, p < 0.05
