Mean change (95% CI) for Hospital Anxiety and Depression Scale (HADS) depression scores by readmission status. Interval estimates with lower and upper limits were plotted for mean depression scores on the HADS at baseline, 90 days and 12 months by hospital readmission status. At 12 months confidence limits do not overlap showing that depression was significantly worse among readmitted patients compared with patients who were free of readmissions.
