Summary of random effects model examining the relation of subtypes of hallucinations with baseline level of and rate of change in the composite measure of cognitive function. Terms for age, education, sex, race, parkinsonism, and their interactions with time were also included in the analysis

Model terms	Mean estimate	SE
Time	−0.48^2-165	0.04
Visual hallucinations	−0.20^2-150	0.10
Visual hallucinations×time	−0.12	0.07
Auditory hallucinations	−0.18	0.12
Auditory hallucinations×time	−0.16	0.10
Both hallucinations	−0.50^2-165	0.09
Both hallucinations×time	−0.33^2-165	0.07

The mean estimate is the average change in the cognitive score associated with a one unit change in the model term.
