Groups were separated into subjective cognitive decline item endorsers and non-endorsers based on their endorsement of each SCD question. T-tests compared the groups on Geriatric Depression Scale (GDS) scores and cognitive composite scores. SD, standard deviation; t, T statistic; df, degrees of freedom; p, significance, two-tailed.
