Establishing a composite endpoint for measuring the effectiveness of geriatric interventions based on older persons’ and informal caregivers’ preference weights: a vignette study

Table 2 Results of mixed linear analyses with as dependent variable the GWB scores given by all raters

	Older persons and informal caregivers (N = 200)

Self-perceived QoL	−0.03	−0.02	0.29	−0.07	0.02

Note 1: The unstandardized coefficients estimate the increase in the dependent variable (general well-being scores) per unit increase of the continuous predictors.
Note 2: The unstandardized coefficients are the preference weights of the components included in the composite endpoint.
