Figure 3

Comparison of ET scores among the three groups ( ¯x ± s) Note: the abscissa denotes before and after intervention, and the ordinate denotes ET score, ng/L. The ET levels of patients in control group A before and after intervention were (67.14 ± 21.68) ng/L and (47.96 ± 14.66) ng/L, respectively. The ET levels of patients in the control group B before and after the intervention were (66.73 ± 21.46) ng/L and (38.04 ± 11.13) ng/L, respectively. The ET levels of patients in the combined group before and after intervention were (66.95 ± 21.53) ng/L and (29.77 ± 10.61) ng/L, respectively. A significant difference in the comparison of ET levels between control group A and control group B after intervention (t = 7.961, ). A significant difference between the control B group compared with the combination group in terms of post-intervention ET levels (t = 4.916, ). A significant difference in the comparison of ET levels after intervention between the control A group and the combination group (t = 3.615, ).
