Associations between participant Cogstate scores and SP-ECog. Scatterplots showing associations between SP-ECog and Cogstate scores on four Cogstate Brief Battery subtests (DET, IDN, ONB, and OCL; shown in different columns) in (A) all participants; (B) CU participants with no SMCs; (C) CU participants with SMCs; (D) participants with self-reported previous diagnosis MCI; or (E) participants with self-reported previous diagnosis of AD. Solid red lines are linear regression lines, and dotted black lines show the upper and lower confidence intervals, for multivariable regression models. Abbreviations: AD, Alzheimer's disease; CU, cognitively unimpaired; DET, detection task to measure processing speed; IDN, identification task to measure attention; MCI, mild cognitive impairment; ONB, One-Back Test; OCL, One Card Learning; SMC, subjective memory concern; SP-ECog, study partner-reported Everyday Cognition scale score.
