Fig. 1. ROC curves for the Inbrain CST total score in the comparison between (A) the SCD group and the cognitively impaired group (aMCI + AD dementia), (B) SCD and aMCI, (C) the non-dementia group (SCD + aMCI) and the AD dementia group.

ROC = receiver operating characteristic, CST = Cognitive Screening Test, K-MMSE = Korean-Mini Mental State Examination, SCD = subjective cognitive decline, aMCI = amnestic mild cognitive impairment, AD = Alzheimer's disease.
