SCD-Q My-Cognition	SCD-Q Their-Cognition		Total, n (%)
	Study partner’s non-SCD, n (%)	Study partner’s SCD, n (%)
Non-SCD, n (%)	220 (70.06)	7 (2.23)	227 (72.29)

SCD-Q My-Cognition in the rows, and SCD Their-Cognition in the columns, representing participant-partner contingency by SCD status, respectively. Data corresponding to the control group presented in cell [1, 1], data corresponding to the group of unaware decliners in cell [1, 2], data corresponding to SCD not confirmed by the study partner in cell [2, 1], and data corresponding to aware decliners in cell [2, 2].
