Random-Effects Logistic Regression Model Showing the Relationship between Statin and Free of Delirium, Adjusted by CRP

	Statin + CRP: Free of Delirium
	(n = 225; Person-Days = 1,117)
	OR	95% CI	P Value
Statin	1.56	0.64–3.79	0.32
CRP	0.68	0.51–0.90	0.01
Age, per year	0.99	0.96–1.02	0.46
Sex, women vs. men	0.62	0.25–1.53	0.30
mSOFA, per point	0.60	0.48–0.76	<0.01
Sepsis, yes vs. no	2.46	0.95–6.36	0.06
Propensity score*	3.63	0.41–31.8	0.24
Ventilated, yes vs. no	0.74	0.68–0.81	<0.01
Elective vs. emergency	17.6	3.96–78.1	<0.01

Definition of abbreviations: CI = confidence intervals; CRP = C-reactive protein; mSOFA = Sequential Organ Failure Assessment (minus Glasgow Coma Score); OR = odds ratio.

CRP quantities log_(e) transformed to obtain normal distribution. When used as a dependent variable, OR is per increase in standard deviation of log_(e) CRP.

All models allow for random-effects for each individual.

^*Propensity score according to age, sex, primary hypercholesterolemia, ischemic heart disease, diabetes, peripheral and cerebrovascular disease, and admission for aortic aneurysm surgery.
