The mean of the overall quality of life and standard deviation before the intervention was 40.46 ± 2.58 in the check team and 40.30 ± 7.25 in the intervention team. The results of independent t-test showed that the two teams were homogeneous before the intervention (P = 0.125). Also, both teams showed no clear distinction in any of the eight concepts of the quality of life (p > 0.05) before the intervention (Table 2).
