Comparison of ANF scores among the three groups ( ¯x ± s) Note: the abscissa indicates before and after the intervention, and the ordinate indicates the ANF score, ng/L. The ANF levels of patients in control group A before and after intervention were (419.68 ± 110.13) ng/L and (299.15 ± 88.37) ng/L, respectively. The ANF levels before and after intervention in control group B patients were (418.57 ± 109.42) ng/L and (251.76 ± 59.62) ng/L, respectively. The ANF levels of (419.35 ± 110.05) ng/L and (236.79 ± 41.27) ng/L before and after the intervention in the combination group patients, respectively. A significant difference in ANF levels in the control A group compared to the control B group after the intervention (t = 8.980, ). Asignificant difference in ANF levels in the control B group compared to the combination group post-intervention (t = 5.726, ). A significant difference in ANF levels in the control A group compared with the combination group after the intervention (t = 2.982, ).
