AUCs for the delirium susceptibility score for any, prevalent and incident delirium

	AUC
	Any n = 205	Prevalent n = 205	Incident n = 150
Weighted score	0.78, 0.71–0.84	0.71, 0.64–0.79	0.81, 0.70–0.92
Unweighted score	0.78, 0.72–0.85	0.73, 0.66–0.80	0.79, 0.69–0.90
After removal of individual factors from the weighted model
Without visual impairment	0.77, 0.71–0.84	0.71, 0.64–0.79	0.81, 0.70–0.92
Without cognitive impairment	0.70, 0.63–0.78	0.66, 0.59–0.75	0.72, 0.59–0.84
Without infection	0.72, 0.65–0.79	0.66, 0.58–0.74	0.77, 0.66–0.88
Without age	0.80, 0.74–0.86	0.74, 0.67–0.81	0.84, 0.77–0.92
Without SIRS	0.76, 0.69–0.82	0.69, 0.62–0.77	0.72, 0.59–0.84
After addition of other factors contained in existing models to the weighted model
With clinical dehydration	0.78, 0.65–0.80	0.73, 0.65–0.80	0.80, 0.69–0.91
With functional impairment	0.76, 0.70–0.83	0.72, 0.64–0.79	0.78, 0.67–0.89

AUCs are shown for both weighted and unweighted models and for the weighted model after removal of each factor in the model in turn and after the addition of other factors contained in existing models.
