Mean change (95% CI) for St George's Respiratory Questionnaire (SGRQ) by readmission status. Interval estimates with lower and upper limits were plotted for mean SGRQ scores at baseline, 90 days and 12 months by hospital readmission status. At 12 months confidence limits do not overlap showing that HRQOL was significantly worse among readmitted patients compared with patients who were free of readmissions.
