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