Data were presented as mean ± SD. Nonparametric analysis – Wilcoxon sign rank test was used for within-group analysis and the Mann-Whitney U test was used for analysis between groups.
*p < .05 intragroup comparison; **p < .05 between group comparison.
Time point 1 & T1: baseline, Time point 4 & T4: one week after discharge.
