General cognitive performance (GCP) over time using the four retest correction methods. Models 1-3) SAGES surgical sample by delirium group: Delirium-negative (n = 426, solid line, 95% C.I.s in dark gray) and Delirium-positive (n = 134, dashed line, 95% C.I.s in medium gray); Model 4) SAGES surgical sample by delirium group and non-surgical comparison (NSC) sample (n = 118, dotted line, 95% C.I.s in light gray). X-axis: assessment time point (months since surgery); Y-axis: model-based estimated GCP at the means of covariates (age = 77 years, 56% female, 1% nonwhite race/ethnicity, education = 15 years)
