ROC curve analysis for the detection of amyloid PET positivity. ROC curve analysis in the total participants from the J-TRC cohort (n = 474) (A), in the CDR 0 participants from the J-TRC cohort (n = 331) (B), and in the CDR 0.5 participants from the J-TRC cohort (n = 143) (C), in the total participants from the BioFINDER cohort (n = 177) (D), in the CU participants from the BioFINDER cohort (n = 114) (E) and in the MCI participants from the BioFINDER cohort (n = 63) (F). CDR: clinical dementia rating (global score), CU: cognitively unimpaired, MCI: mild cognitive impairment
