1. NPI scores: means and S |
E from analysis o |
untransformed data; p values from | ||
analysis of square-root transformed data, significant covariates were GDS
(p=0.01) and RCS (p=0.02).
2. QUALID ; significant covariates were GDS (p=0.006) and RCS (p=0.0003).
3. Six covariates differed at baseline: TESS-NH safety score, QUIS positive social
score, RCS total score, GDS score, country of birth and number of co-morbid
diseases.
4. p values from hierarchical linear models with all three time points included as
outcomes: p(Group) is for main effect of intervention, p(Time) is for main effect
of time (over three time points) and p(GxT) is for the interaction between group
and time.
