Boxplots showing the mean 10-fold classification accuracy, sensitivity, and specificity with their 95% confidence intervals for bvFTD vs each individual cohort and the whole mixed dataset using age + sex + anteroposterior ventricular ratio alone and together with other volumetric ventricular features. Abbreviations: MCI: mild cognitive impairment; AD: Alzheimer’s disease; BV: behavioral variant; SV: semantic variant; PNFA; progressive non-fluent aphasia. APR: anteroposterior ratio; TVV: total ventricular volume; LRTR: left/right temporal ratio; left/right frontal ratio.
