Notes: Model 1 N = 786; Model 2 N = 761. Model 1 include age and sex as covariates. Model 2 further include the time gap between personality assessment and the blood collection, eGFR, years of education, race (other vs. white), smoking, physical activity, body mass index, and disease burden. L95%CI and U95%CI are the lower and upper bound of the 95% Confidence interval. p < .05 and related β are bolded.
