Probability of institutionalisation, or death, during the 18-month GERAS study, according to baseline AD dementia severity

	Mild AD dementia	Moderate AD dementia	MS/S AD dementia	Overall
Probability of being institutionalised at 18 months, %	9.0	17.9	28.0	17.2
95% CI	5.6; 14.3	12.7; 24.7	21.0; 36.7	14.1; 21.0
Probability of death at 18 months, %	5.3	6.5	14.9	8.2
95% CI	2.9; 9.6	3.5; 11.7	9.6; 22.7	6.0; 11.1

The Kaplan–Meier method was used to calculate probabilities and their associated 95% CIs
