Logistic Regression Model Showing Odds of Incident Delirium in Relation to Baseline Cognitive Function

	OR	95% CI	p Value*
MMSE, per point	0.95	(0.92–0.99)	0.018
Age, per year	1.08	(1.00–1.18)	0.056
Sex, women cf. men	2.36	(1.03–5.40)	0.037
Comorbidity score	1.04	(0.90–1.19)	0.636

Notes: N = 468 in 257 clusters. Goodness of fit for model residuals p = 0.053 (Pearson χ² = 426.77). *2-tailed p value used in testing the null hypothesis that the coefficient (parameter) is 0, Wald χ² for 4 degrees of freedom = 20.72. MMSE: Mini-Mental Status Examination.
