^aThe hospital discharged patients.

^bValues are the number of patients with percentages in brackets or mean ± SD.

^cEchocardiographic parameters were compared using the McNemar's test for dichotomous variables, and the Student's t-test, Mann–Whitney U-test or Wilcoxon rank-sum test for continuous variables. The matched and unmatched patients were compared with paired or unpaired tests, respectively.
