*β=mixed linear regression weight for treatment at that point in time. β>0 indicates a higher score in the intervention group. Higher scores or positive change scores indicate a higher perceived quality of care based on the PACIC. Effects in this table are based on the mixed model after deleting the treatment effect at baseline, which was never significant (see the Methods section). Effects before deleting the treatment effect were very similar and agreed with the present table in terms of significance yes/no.
