For the controls versus dementia (FTD) comparison, NfL had the highest AUC value (AUC: 0.89 [95% CI: 0.81–0.98]), and GFAP was the only other marker which showed significant discriminatory performance between the two groups (AUC: 0.75 [95% CI: 0.63–0.88]). This evidence concerns the gene NEFL and dementia.
