Summary of random effects models examining the relations of hallucinations and delusions 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 analyses

Model terms	Mean estimate	SE
Time	−0.47^1-165	0.04
Hallucinations	−0.33^1-165	0.07
Hallucinations×time	−0.22^1-165	0.05

Time	−0.51^1-165	0.04
Delusions	−0.18^1-165	0.07
Delusions×time	−0.08	0.05

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