Linear regression predicting change in AβR from preoperative to POD1. Two outliers were excluded based on Cook's distances for peak DRS-R-98 ∼ POD1 change in plasma AβR. AβR, amyloid beta ratio; AIC, Akaike's information criteria; AUC, area under the curve; BIC, Bayesian information criteria; CI, confidence interval; df, degrees of freedom; DRS-R-98, Delirium Rating Scale-Revised-98; NSQIP-D, National Surgical Quality Improvement Program-risk of death; POD, postoperative day; se, standard error. Number of observations=65; log-likelihood=36.8; AIC=–61.5; BIC=–48.5; residual df=60. ∗P<0.05; ∗∗P<0.01; ∗∗∗P<0.001.
