  1. *Paired t-test to compare the mean scores at baseline and at 6 months after discharge
  2. SD standard deviation, SES standardized effect size, SRM standardized response mean, CI 95% confidence interval
  3. MLHFQ physical subscale scores range from 0 to 40, emotional subscale scores from 0 to 25, and total scores from 0 to 105, with higher scores indicating worse health status. Changes were calculated by subtracting follow-up scores from baseline scores; a positive result indicates a gain in quality of life
  4. abc Superscript letters indicated differences among the three subgroups (improved, equal, and worsened) according to Scheffe’s test for multiple comparisons at P < 0.05
