Fig. 1: Inter-rater reliability reviewers’ agreement with the primary site consensus diagnosis.

This figure displays the agreement on consensus diagnoses among the primary site and two raters across diagnostic categories (Normal/SCC, MC, AD, PDD). The x-axis counts the participants, and the y-axis lists the diagnoses. Blue bars show the primary site’s consensus, with darker and lighter shades indicating the agreement between Rater 1 and Rater 2. Total agreement is highlighted at the top, showing high consistency, especially in Normal/SCC and AD, with minor discrepancies in PDD. This aids in assessing the diagnostic alignment across different evaluators. SCC subjective cognitive complaint, MCI mild cognitive impairment, AD Alzheimer’s disease, PDD Parkinson’s disease dementia.
